Insert Bearings
Turner insert bearings are replaceable components designed for use in our mounted ball bearing units, allowing worn bearings to be replaced without changing the entire housing assembly. Each series is engineered for a unique combination of load requirements and operating conditions, with different locking methods used to secure the inner ring to the shaft.
SB200 & CSB200 Series
SB and CSB inserts are light-duty ball bearing inserts with set screw locking and a narrow inner ring profile designed for compact installations. Their reduced width makes them well-suited for auxiliary shafts, small conveyors, light agricultural equipment, and other space-constrained applications with low to moderate load demands.
SB inserts feature a spherical outer diameter that allows for self-alignment within compatible housings. CSB inserts have a cylindrical outer diameter and are typically used in applications where the bearing is installed directly into a machined bore rather than a standard mounted housing. This makes them suitable for equipment where alignment is controlled by the surrounding structure.
Annealed set-screw ports and 120° screw spacing help maintain inner-ring roundness, reduce cracking risk, and support consistent shaft retention.
Narrow inner rings support compact installations where space is limited.
Spherical and cylindrical outer diameter options support self-aligning mounted applications (SB) or bore-mounted configurations (CSB).
Available in relubricatable and non-relubricatable configurations. Relubricatable options allow grease to be replenished through the housing zerk and outer ring port, while “N” suffix options are factory-lubricated and sealed for applications with space or maintenance constraints.
The Turner Advantage
SAE 52100 steel inner and outer rings provide consistent hardness and fatigue resistance that increases service life.
Optional L3 triple-lip seals increase sealing contact for better protection in severe contamination conditions.
Steel retainers improve durability under heat, shock, and variable loading compared to polymer cages.
Available with Lubrilife permanent lubrication for maximum contamination protection without routine maintenance.
Standard contact seals retain grease and block common industrial contaminants.
