| Double direction axial angular contact industrial ball bearings are non self-retaining precision bearings with restricted tolerances to class SP. They comprise solid shaft locating washers, spacer rings, housing locating washers and ball and cage assemblies with solid brass cages. The parts of the professional bearings are matched to each other and can be fitted independently of each other; they must not be interchanged with those of bearings of the same size. |

SNR TOPLINE manufacturer of 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 industrial 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.

Four point contact professional bearings are single row angular contact ball bearings and therefore require significantly less space in an axial direction than double row designs.
The bearings comprise solid outer rings, split inner rings and ball and cage assemblies with brass or polyamide cages. Due to the two-piece inner rings, a large number of professional balls can be accommodated. The halves of the inner ring are matched to the specific bearing and must not be interchanged with those of bearings of the same size. The outer ring with the ball and cage assembly can be fitted separately from the halves of the inner ring. |

In particular, precision tapered roller bearings manufacturer feature:
tighter manufacturing specifications resulting in greater rotational accuracy;
reduced tolerances on bore and outside diameter creating improved performance in high speed, high temperature applications;
straight race and/or industrial roller profile designs (versus crowned profile designs) for increased accuracy and rigidity;
controlled machining and assembly processes to ensure that components are matched properly and exact specifications are met;
high load-carrying capabilities so that bearing manufacturer fatigue life is enhanced;
the ability to be adjusted during installation so that operating torque, shaft rigidity and operating temperature can be precisely controlled.

High temperature manufacturer of 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 industrial roller bearings). Please contact SNR's technical departments.
Applications examples: professional oven carriages, transport rolls, conveyors supplier, 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 manufacturer are double row, self-retaining units comprising solid outer rings with a concave raceway, inner rings with a cylindrical or tapered bore and ball and cage assemblies. The suppliers of bearings are available in open and sealed versions. |
|
The SNR single-row radial contact ball bearing range is suitable for the most diversified applications. Designed essentially to sustain moderate radial loads, these professional 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 Industrial seal or baffle
• Normal or increased clearance (C3). Other clearance categories are available on request.

NSK manufactures a complete range of metric single row angular contact manufacturer of bearings from 10mm to 775mm bore diameter. The standard contact angles available are 15, 25, 30 or 40 degrees. A range of inch sizes is also available with a standard 20 degree contact angle.
These bearings are capable of supporting radial loads and axial load in one direction. The larger the contact angle, the higher the axial load carrying capacity. For high-speed operation, however, smaller contact angles are preferred.
Normally these bearings are used in duplex pairs in order to support axial loads in either direction. They can be supplied paired back-to-back or face-to-face with known preloads or clearances built-in. They can also be supplied paired in tandem to accept exceptionally heavy axial loads in one direction.
The most popular contact angle for industrial bearings is 40 degrees and these can be supplied with different cage materials including steel, brass or polyamide.

Single row angular contact ball bearings manufacturer are self-retaining units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet steel or brass cages. The raceways of the inner and outer rings are offset in relation to each other in the direction of the bearing axis. The bearings specifications are available in open and sealed versions. Their self-alignment capacity is very small.
Many sizes of angular contact ball bearings are supplied in X-life design. These bearings are indicated in the dimension tables. Bearings of X-life quality have an improved raceway geometry as well as optimised surfaces. This gives a significant increase in the fatigue limit load of the bearings. In calculation of the expanded adjusted rating life, values up to 50% higher are achieved. In certain applications, a smaller design of bearing arrangement can therefore be used if necessary.
Double row angular contact ball bearings are units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet steel or brass cages. They correspond in design to single row angular contact ball bearings in pairs in an O arrangement but give a narrower design than these. They differ in the size of their contact angle and the design of the bearing rings.
