1/2" Bore 2-Bolt Flange Bearing
The Timken RCJT 1/2 is a cast-iron housed ball bearing unit with a 1/2 inch bore. It uses an eccentric locking collar to secure the shaft in light-duty power transmission applications. The unit is supplied new and ready for installation. It is not suited for buyers who need a larger bore diameter or a four-bolt mounting pattern.
Capacity and Load Limits
The bearing delivers a dynamic load capacity of 2,400 lb and a static capacity of 1,060 lb. These ratings provide headroom for moderate radial loads in conveyor, fan or agricultural equipment. The grease fill uses Mobil Polyrex EM or an NLGI #2 equivalent for standard operating conditions. It cannot support heavily shocked or continuously overloaded shafts beyond these stated limits.
Temperature and Material Constraints
The 52100 chrome steel insert operates reliably from -65 °F to 200 °F. The cast-iron housing and standard lubricant define the practical thermal envelope for continuous service. Operation outside this range risks lubricant breakdown or reduced bearing life. The design does not accommodate high-speed precision spindles or environments requiring stainless-steel corrosion resistance.

Questions about this item
Will the 3 in bolt-hole spacing match the existing mounting pattern on my older frame?
The bearing uses a 3 in bolt-hole center-to-center dimension with 3/8 in bolts, so it fits the same pattern used on many legacy flanges.
How can I confirm the eccentric locking collar is gripping the shaft correctly after installation?
Tighten the collar in the direction of shaft rotation until it seats, then verify there is no axial play and the setscrew is secure.
Does the box include the Mobil Polyrex EM grease or must I purchase NLGI #2 equivalent separately?
The unit ships pre-lubricated with Mobil Polyrex EM; no additional grease is required for initial operation.
