Type: Machine tools and other precision applications require superior bearing performance. Extended speed capability, a high degree of running accuracy, high system rigidity, low heat generation, and low noise and vibration levels are just some of the performance challenges. They are single direction thrust bearings and therefore are usually found with an opposing bearing unless the axial load is always in one direction. They are most commonly used in pairs which are supplied as matched sets these can be found in our precision bearings section.


Brand: Our bearings come with choices of brands, our premium brand is NSK/RHP who produce the highest quality precision bearings used by many high profile organizations. Branded is a guaranteed quality brand, it will be one of the following S#K#F-SNFA/F#A#G-Barden/IBC. All these brands are recognized for their quality.


Contact Angle:It should be noted that different applications need different thrust angles of contact. We offer 15 degree angle (CTR) or a 25 degree angle (A5TR). With two contact angles to choose from, designers can optimize their application based on axial load carrying capacity, speed capability and rigidity. Each bearing has the largest possible number of balls to provide the highest possible load carrying capacity


Arrangement:The choices here are either single or double (pairs), Universally matchable bearings and matched bearing sets can be arranged in various combinations depending on the stiffness and axial load requirements, we can however offer triples and quads so please call if these are required.


Preload: To meet the varying requirements regarding rotational speed and rigidity, bearings are produced to different preload classes:

-Class A, Light preload

-Class B, Moderate preload

-Class C, Heavy preload


Precision Accuracy: Super-precision angular contact ball bearings are made to P5 or P4 tolerance class, in accordance with ISO 492:2002, as standard.
