NSK manufactures a full range of metric and inch size mini ball bearings with bore diameters of less than 10mm. These can be divided into two basic types, deep groove and angular contact ball bearings manufacturer.
Deep groove ball manufacturers of bearings are the most common and NSK offer several variants for miniature sizes:
Standard type
Flanged outer ring type
Extended inner ring type
Synchro bearings with thick section outer rings
Extra-thin section type
In addition, NSK can also provide these bearings with shields or professional seals (contact or non-contact) on one or both sides of the bearing and pre-lubricated with grease.
For applications requiring higher speed, rigidity or axial load capacity, then miniature angular contact bearings are also available.

Ball bearings
Ball bearings supplier are machinery components, which comprise an outer ring, inner ring, professional balls, professional retainers, shields and snap rings. Small bearings and small-sized ball bearings have up to 30mm in external diameter. Essential to high-precision rotary components, ball bearings determine rotational accuracy.
Bearing types include Radial ball bearings (Deep Groove and Angular Contact) and Thrust ball bearings. Journal bearings are designed to carry both radial and axial (thrust) loads, while thrust bearings are designed for pure thrust loads only. Many different configurations are available for ball bearings.
Miniature Bearings
Our miniature bearings range in sizes from .1181 to 1.000 inch O.D. (3mm to 26mm), and are available in inch and metric sizes.
Miniature bearings and instrument bearings are single row bearings. The construction of these miniature bearings enables them to carry moderate radial and thrust loads at low operating torque while providing high performance within a small envelope design. Miniature bearings and instrument bearings are typically available in both stainless steel for those applications requiring corrosion resistance and chrome for maximum fatigue life.
Minebea manufactures more than 8,500 different types of miniature and small-sized bearings, most of which have external diameters of 22mm or less. |

The bearings manufacturers of industrial rotating equipment operate under arduous conditions - often for considerable periods of time. The most reliable indicator of bearing condition is the temperature of the metal beneath the professional shoe.
Recognition of rising temperature can provide a warning of the breakdown of the lubricating oil film; thus allowing machine shutdown and maintenance to take place - avoiding the probable catastrophic failure of the bearing and possible damage to its mounting. Conax Compact bearing Sensors provide a simple and cost-effective method to monitor bearing temperatures.
Features:
- For embedded applications in rotating machines
- RTDs - 100 ohm platinum, 0.00385 ohm/ohm/°C
- Supplier of thermocouples types J, K, T & E
- Single and duplex sensors
- Various styles and sizes
- Operating Temperature: to 250° F ( 120° C) |

Small bearing (MBS) Sensor
A critical indication of the status of bearings suppliers on large rotating plant is provided by their running temperature.
Due to its small physical size the miniature bearing sensor can be positioned close to the bearing surface allowing it to sense any early change in temperature.
These devices are available in both thermocouple and PT100 resistance industrial thermometer format and can be supplied as either single or duplex sensors. The sensor lead wire insulation is in PTFE and if necessary lead wire jackets can be protected with stainless steel outer braid.
BSWS Bearing sensor wire industrial seal assemblies are low temperature/low pressure glands for embedded sensors to prevent oil wicking along the sensor leads. They seal on the individual insulated leads exiting an oil-filled bearing housing.
Typical aplications are motors, turbines, pumps & journal bearing pedestals. |
