Conventional all steel bearings limit design potential as technology requirements roll forward at a fantastic rate. Ceramic Hybrid bearings offer a long list of characteristics far superior to that of conventional all-steel bearings.
Ceramic hybrids are a mixture of steel races and ceramics balls. The most common ceramic ball used, because of its hardness, is the Silicon Nitride (Si3N4) ball, although in certain environments either Zirconia (ZrO2) or Alumina Oxide (Al2O3) can be used. Ceramic hybrids offer higher RPMs due to the non-porous ball surface, longer life due to having a greater Rockwell hardness than steel and decreased weight as a result of being 2/3 the weight of steel. Ceramic hybrids are ideally suited to any application looking to achieve increased speed, durability and heat dissipation.
Stainless Steel Series: Stainless Steel resists corrosion in atmospheric, pure water environments as well as most acids, alkaline solutions, and chlorine environments. The easy cleaning ability of stainless makes it the first choice for strict hygiene conditions, such as dental tools, hospitals, kitchens and other food processing envoronments.
Ultra Seals Series: The Ultra Seal is a non-contact, frictionless seal that is placed beneath the metal shields. Say goodbye to dirt, dust and other contaminants without any increased drag. These bearings are maintainence free and lubed for life.
Ceramic Hybrid Series: Ceramic is the new Holy Grail! Its lighter, smoother, stiffer, harder, corrosion resistant, and electrically resistant. These fundamental characteristics allow for a wide range of performance enhancements in bearings.

The xiros® polymer ball bearings are single-row grooved ball bearings based on DIN 625. The lubricant-free and maintenance-free ball bearing consists of four components.
- The outer ring
- The inner ring
- The cage
- And the balls
The inner and outer rings are made of igus® tribopolymers to maximize service life and minimize coefficients of friction. In contrast to metallic ball bearings, xiros® polymer ball bearings manage absolutely without lubrication. For this reason they are suited for a multitude of applications that depend not on extreme rotary speeds or loads, but just on lubricant-free application in contrast to permanently lubricated metallic ball bearings. These areas are for example food and medical industries, packaging and textile industries, or the chemical industry and cleanroom applications as well as electronics and office technology.

Deep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies. These products are of simple design, durable in operation and easy to maintain; they are available in single and double row designs and and in open and sealed variants. Due to the production technology used, open bearings can still have turned recesses on the outer ring for seals or shields.
|
|
Radial insert ball bearings are single row, rady-to-fit units comprising a solid outer ring, an inner ring extended on one or both sides, cages made from plastic or sheet steel and P, R, L or T seals. Bearings with an inner ring extended on both sides undergo less tilting of the inner ring and therefore run more smoothly.
The outer ring has a crowned or cylindrical outside surface. In conjunction with an INA housing matched to the bearing type, bearings with a crowned outside surface compensate for shaft misalignments; see Compensation of misalignments.
They are located on the shaft by means of an eccentric locking collar, grub screws in the inner ring, an adapter sleeve, drive slot or fit. Radial insert ball bearings are particularly easy to fit, suitable for drawn shafts of grade h6 to h9 and, with a few exceptions, can be relubricated.

SNR TOPLINE bearings benefit from SNR's state-of-the-art innovations, providing suitable solutions for the most extreme operating requirements.
This product range breaks down into 4 families, with bearings capable of sustaining temperatures from -60 °C (LT series) to +150 °C (FT series) and up to +200 °C (HT series), as well as high rotational speeds up to 700,000 N.Dm (HV series).
Fitted with steel cages, the Topline bearings are also proposed in sealed version (fluorinated elastomer or Viton seal, according to the series) or in protected version (deflector baffles, of lower cost, and suitable for higher rotational speeds).
The TOPLINE product range greases have been selected for their outstanding performance in application and submitted to thorough testing. 70 % of the bearing failures are attributable to lubrication: therefore, particular care has been paid to grease selection, now a major contributor to the quality of our bearings, guarantying their reliability and durability.

Deep groove ball bearing, featured of simple structure and convenient using, is the kind of bearing that is used the most extensively in the world. With little friction coefficient and high limit speed, it can be used to bear axial load when the rotate speed is too high and thrust ball bearing is not suitable to be used.
ZQZ deep groove ball bearing (open) mainly incudes: 6000, 6200, 62200, 62300, 16000, 6300, 6400, etc.

High temperature bearings
Fitted with a steel sheet cage, the F600 range bearings receive a specific surface treatment making them more resistant to oxidation and thermal shocks, and allowing operations between 200°C and 350°C.
Suitable for slow handling at high temperatures, they require a rotating speed of less than 50 RPM and moderate loads. Radial clearance was increased to compensate for thermal expansion deviations between the 2 rings and for neighbouring component distortions.
The special treatments of the F600 series can be applied on request to other bearing symbols and types (e.g. spherical roller bearings). Please contact SNR's technical departments.
Applications examples: oven carriages, transport rolls, conveyors, porcelain works, glass making, foundries, cement plants, brick plants…
Series: F600 (standard), F604 (greased and protected), F605 (limestone process)
6000, 6200, 6300

Self-aligning ball bearings
With double ball rows and a spherical raceway in the outer ring, self-aligning ball bearings can compensate for installation errors or shaft misalignment.
The SNR double-row self-aligning ball bearings are useful for applications requiring high rotating speeds while exercising moderate radial, and moderate or low axial loading.
SNR proposes an extensive range of self-aligning ball bearings, available with or without seals. Certain Series are fitted with an increased width inner ring (11200, 11300 Series) for easier fitting on shaft.
Technical data:
• Common dimension bearings are fitted with a metallic or synthetic cage (maximum continuous operating temperature = 120°C). Large size bearings are equipped with steel sheet or machined brass cages.
• 2200 and 2300 Series bearings can receive seals.
• Clearance : normal, increased (C3).
Application examples : Long-shaped and flexible shafts, standard industrial applications, chemistry, agriculture…

The SNR single-row radial contact ball bearing range is suitable for the most diversified applications. Designed essentially to sustain moderate radial loads, these bearings, which are the most commonly used, also sustain moderate axial loads in all directions. They are particularly suitable for applications with high rotating speeds and when energy loss limitation is sought.
Technical data:
• Standard steel sheet, or solid cages, or polyamide cages (with 25% glass fibre fill)
• Nitrile Seal or baffle
• Normal or increased clearance (C3). Other clearance categories are available on request.

RBC thin section ball bearings are engineered to solve a variety of
design problems that cannot be solved with conventional ball bearings.
A bearing is considered a thin section when the bore diameter is greater
than four times the radial cross section. Within any thin section bearing
series, the cross section remains constant as the bore diameter changes.
Typically the cross section is twice the ball diameter, and nominal
dimensions are given in inches.
RBC thin section ball bearings are most often found where space limitations,combined loading, and weight restrictions pose unique design
requirements.
