HM (HN) Lock Nuts
HM (HN) Bearing lock nuts are used to locate bearings onto a shaft. Additionally, they can be used to mount bearings with a tapered bore onto tapered shaft seats and adapter sleeves and to dismount bearings from withdrawal sleeves. Lock nuts are also frequently used to secure gears, belt pulleys, and other machine components.
Locking nuts with integral locking reduce the cost of the shaft as no keyway is required. Installation is quicker and easier because no separate locking device is necessary. Chin Sing manufactures the finest quality of bearing lock nut with durable life cycles.
