Ask for Custom SupportSLB Self-Lubricating Spherical Bearings are spherical plain bearings made from an inner spherical ring and an outer race that permit controlled rotation, oscillation, and angular misalignment. The self-lubricating race direction is intended to reduce routine relubrication where the operating conditions are compatible. These bearings are commonly installed in rod eyes, cylinder ends, suspension links, lifting equipment, agricultural machinery, and other slow-moving pivot points. Confirm fit, race material, seals, lubrication, load direction, and edge support before installation.
Spherical plain bearings accommodate angular misalignment and oscillating motion at cylinder eyes, lifting arms, and other pivot connections. Select the race, seals, lubrication, and load direction for the duty cycle.
These bearings are commonly used at heavily loaded pivot points in construction, forestry, agricultural, and material-handling machinery where slow oscillation, shock, contamination, and service access influence the bearing choice.
The spherical inner and outer surfaces support controlled angular movement in suspension links, axle connections, and fabricated mechanisms. Confirm bore fit, housing support, edge loading, and required misalignment before installation.
Used in industrial mechanisms, fixtures, and rugged assemblies where articulated movement, radial load support, and liner-based wear reduction are all required.
Chosen where stainless race or stainless ball options help improve service life in exposed or corrosion-sensitive environments.
Frequently specified for OEM builds that need repeatable load-slot bearing geometry, PTFE-lined articulation, and optional material configurations.
SLB spherical bearings are used in articulated joints and linkage positions where load-slot geometry, reinforced nylon PTFE race construction, and compact radial support are required.
SLB uses a reinforced nylon race with PTFE and load-slot construction, giving it a different wear and articulation profile from standard metal-to-metal spherical bearings.
SLB uses a 52100 bearing steel ball, hard chrome plated and precision ground, together with a heat-treated alloy steel race and a reinforced nylon race with PTFE liner construction.
Yes. Add -SS for stainless race and stainless ball, or -S for stainless race with steel ball, for example SLB12-SS or SLB12-S.
The reinforced nylon race with PTFE helps reduce friction and supports smoother articulated movement in applications that benefit from lined spherical bearing construction.
Start with the required bore, outer diameter, widths, ball size, and static radial load shown in the size chart, then confirm whether standard, -S, or -SS material configuration is the better fit for the application.
