Precision Metal Ball Bearings and Plastic Bearings

for Industrial and Commercial Applications

Bearings

Friction, or resistance to motion, is the result of the force acting between two surfaces as they slide against each other. Bearings reduce friction and provide smooth sliding contact between surfaces due to their material, shape or lubrication. Choosing the correct bearing for an application improves efficiency, extends bearing life at high speeds and avoids overheating. Bearings fall into two general categories: radial bearings that support rotating shafts and thrust bearings that support axial loads. Four classifications of bearing tolerances have been established, providing standards of precision for the correct application of ball bearings.

The designations are:
ABEC 1, ABEC 5, ABEC 7 and ABEC 9, ABEC 9 being the most precise.

SDP/SI carries a wide range of bearing types and materials suitable for industrial and commercial applications. Self-lubricating plastic bearings are light weight and work well in applications where abrasive and corrosive conditions exist. Both plain bearings (sleeve bearings and thrust bearings) and anti-friction bearings (ball bearings, roller bearings, and needle bearings) are offered. Standard catalog items include: precision ball bearings, plastic race ball bearings, self-clinching & self-aligning pressbearings, needle roller bearings, linear bearings, thrust bearings, plain and flanged sleeve bearings, sintered bearings, rod ends and much more.

Our bearing products combined with our design, engineering, and manufacturing services will make your job easier and your product a success.


Commercial Ground Metal Balls

Commercial Ground Metal Balls


Hardened Steel Balls, 52100 Chrome Steel or 440 Stainless Steel are available in diameters of .0625 up to .5. Balls are hardened to RC 55-62.


Commercial Plastic Balls

Commercial Plastic Balls


Lightweight Nylon Balls provide maximum strength while able to withstand shock. Plastic balls are available in 19 diameters ranging in size from .09375 thru 1.0.


Commercial Ball Bearings

Commercial Ball Bearings


Ball Bearings are made of hardened rolling elements and races, a separator is used to space the rolling elements and reduce friction. This shielded or sealed bearing is widely used in instruments and machines to minimize frictions and power loss. The deep groove ball bearing is the most versatile with sealed grease lubrication. Radial loads and thrust-load capacities may be approximately equal in this bearing. With the proper separator it is very good for high-speed operation. A separator of steel ribbon is used for intermediate speeds and at low speeds, no bearing separator is needed. Because of the simple design and the elimination of a separate lubrication system, these bearings can be found in numerous applications.
