Metal Precision Bearing Balls | Brass & Steel Balls | G.L. Huyett

Metal Precision Bearing Balls. Precision balls, also referred to as loose ball bearings, are precision ground spheres used as rolling elements in ball bearing asselies. The surface is fine finished and through hardened for handling high load capacities. Precision balls are used in a wide variety of appliions ranging from ball bearing

Balls - Enduro Bearings

Ball Grade: Rounder Spins Smoother. Balls are rated by their grade. A Grade 3 ball means that the ball is 3/1,000,000” tolerance of sphericity, and so is extremely round. In fact, the races of any bearing can’t come close to this level of precision in their trueness, but every component being closer to perfect helps decrease friction.

Stainless Steel Balls For Bearings | Precision Grade Balls | BSC

Balls. The most common ball material used in ball bearings is stainless steel, but they can also be manufactured from silicon nitride ceramic, plastic or even glass. Spherical balls, while most commonly used in ball bearings, have more appliions such as in freewheel mechanisms. Balls are responsible for the friction-free, precision rotary

Bearing Grades and Quality - Fit Werx

As mentioned above, because ABEC bearing grade only reflects precision of dimensions, you need to be careful that you still get what you want in other important aspects of bearing performance. For example, ABEC ratings don’t take materials or hardness into account and thus you can have an ABEC Grade 5 steel bearing, Grade 5 Ceramic or Grade 5 “hybrid” bearing.
