/552-Single-Cups-(Imperial)-Dimensions.webp)
The 552 single cup is an imperial-sized tapered roller bearing cup, measuring 4.29″ x 4.875″ x 1.3125″. Made from durable chrome steel, it’s built to handle heavy loads and fits well with Timken equivalents.
Its standard design ensures easy installation, while the precise tolerances (+0.001″ to 0 on outer diameter) provide reliable performance. The cup works in temperatures from -30°C to 110°C.
This cup is part of the 555 series and pairs with multiple cones (like 554, 555, or 560). Ideal for industrial machinery or vehicle axles where tapered roller bearings are needed.
Compliant with RoHS and REACH standards, it’s a practical choice for replacements or upgrades. The 0.13″ backface radius adds to its durability.
