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 comme
rcial 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.
Self-lubricating, oil-impregnated bronze Spherical Bearings are available with bores 4 mm to 12 mm. Felt washers and spring steel retainers are offered for use with the spherical bearings.
Commercial & Precision Thrust Bearings & Components
Thrust Bearings are offered in a variety of configurations, materials and sizes. Both inch and metric dimensioned thrust bearings are available as standard catalog items. General purpose polymer, high-temperature polymer and industrial grade polymer thrust washers are also offered.
