This Buyers Products 2-bolt flange bearing with an eccentric locking collar handles high-speed driveline applications without risking drive shaft slippage. It suits remote-mount hydraulic pumps and shaft-driven equipment where a compact, serviceable bearing is needed. Eccentric locking collar keeps the drive shaft from slipping, even at high RPM. Self-aligning design allows for a small amount of shaft misalignment. One-piece cast iron housing makes the flange rugged and extends bearing life. Included grease fitting keeps maintenance simple and operation smooth. Standard 2-bolt mounting pattern installs easily in tight places. Specifications Bore diameter: 1.000 in.
