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 correct application of ball bearings. The designations are, ABEC 1, ABEC 5, ABEC 7 and ABEC 9, ABEC 9 being the most precise.
SDPSI 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 mechatronic design, engineering and manufacturing services will make your job easier and your product a success.
