BOW Plummer Blocks are available with durable cast-iron housing and various sealing options to keep lubrication in and contamination out. With a facility for easy mounting and dismounting of pre-assembled shafts these products are manufactured with high quality standard.
Adapter sleeves are the most commonly used components for locating bearings with a tapered bore onto a cylindrical seat as they can be used on plain shafts or stepped shafts.
They are easy to install and require no additional location on the shaft. When used on plain shafts, the bearing can be located at any position on the shaft. When used on stepped shafts together with an L-shaped spacer ring, the bearing can be accurately positioned axially, thereby facilitating bearing mounting and dismounting.
Withdrawal sleeves can be used to mount bearings with a tapered bore onto the cylindrical seat of stepped shafts . The sleeve is pressed into the bore of the bearing inner ring, which abuts a shaft shoulder or similar fixed component. The sleeve is located on the shaft by a nut or an end plate. KM or HM lock nuts (Lock nuts requiring a keyway) with appropriate locking devices are suitable.
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 sec ure gears, belt pulleys and other machine components.
