Spherical plain bearings and rod ends

Radial spherical plain bearings requiring maintenance are available with sliding contact surface combination steel/steel in different designs (table 1). They are suitable for heavy static loads and shock loads.

SKF Explorer plain bearings are available with sliding contact surface combination steel/steel in different designs (table 2). They are suitable for heavy static or alternating loads as well as shock loads in applications with low to moderate levels of contamination and no relubrication should be done since lubricated for life.

Maintenance-free radial spherical plain bearings with sliding contact surface combination steel/PTFE sintered bronze (table 3) and those with steel/PTFE fabric (table 4) are suitable for heavy, constant direction loads, where low friction is required. They have a limited suitability for alternating loads as well as shock loads.

Bearings with sliding contact surface combination steel/PTFE FRP (table 5) are suitable for heavy, constant direction loads, where low friction is required. They have a limited suitability for alternating loads as well as shock loads and they are relatively insensitive to contaminants.

Angular contact spherical plain bearings (table 6) are available with sliding contact surface combination steel/PTFE FRP which are suitable for single direction axial loads or combined axial and radial loads. They have low coefficient of friction and are relatively insensitive to contaminants.

Bearings with sliding contact surface combination steel/PTFE fabric are suitable for single direction axial loads or combined axial and radial loads. They have very high load carrying capacity and low coefficient of friction.

Angular contact spherical plain bearings with sliding contact surface combination steel/steel are suitable for heavy single direction axial loads or heavy combined axial and radial loads as well as heavy alternating loads.

Thrust spherical plain bearings (table 7) are available with sliding contact surface combination steel/PTFE FRP which are suitable for single direction axial loads or combined axial and radial loads. They have low coefficient of friction and are relatively insensitive to contaminants.

Bearings with sliding contact surface combination steel/PTFE fabric are suitable for heavy single direction axial loads or combined axial and radial loads. They have very high load carrying capacity and low coefficient of friction.

Thrust spherical plain bearings with sliding contact surface combination steel/steel are suitable for heavy single direction axial loads or combined axial and radial loads as well as heavy alternating loads.

Rod ends with a threaded shank requiring maintenance are available with sliding contact surface combination steel/steel (table 8). They are suitable for heavy static or alternating loads as well as shock loads.

Rod ends with a slotted shank (table 9) can be secured by tightening bolts and are therefore suitable for hydraulic cylinders.

Rod ends with sliding contact surface combination steel/bronze (table 10) have lower load carrying capacity compared to steel/steel rod ends, but are more suitable for applications where lubricant starvation might occur.

Rod ends with a welding shank are available with sliding contact surface combination steel/steel (table 11). They are suitable for heavy static or alternating loads as well as shock loads.

SKF Explorer rod ends are available with sliding contact surface combination steel/steel in different designs (table 12). They are suitable for heavy static or alternating loads as well as shock loads in applications with low to moderate levels of contamination and no relubrication should be done since lubricated for life.

Maintenance-free rod ends (table 13) with sliding contact surface combination steel/PTFE sintered bronze and those with steel/PTFE fabric are suitable for heavy, constant direction loads, where low coefficient of friction is required. They have a limited suitability for alternating loads as well as shock loads.
