Plummer Block Housings help to form bearing units, with Self-aligning Ball Bearings and Spherical Roller Bearings. They permit flexibility in the choice of bearing, location on shaft, seals and lubrication. Made on a modular principle using Cast Iron HT 200 JIS 5501, KG housings are available in a wide range of sizes to suit various application requirements.
To allow slight adjustment in the position, KG Plummer Block Housings have two elongated holes for attachment bolts. The bearing seat in the housing bore is designed for non-locating bearing arrangements. The bearing can move slightly in either direction to compensate shaft elongation, which may happen due to thermal expansion.
Plummer Block Housings offer:
- Low weight to strength ratio
- Ease of mounting and dismounting
- High strength and rigidity
Generally bearings used in a Plummer Block are lubricated with grease, since it lasts for a longer time. Plummer blocks do not have re-lubrication holes. However, bearing performance should be periodically monitored to ascertain re-lubrication requirements.
Special felt seals are provided along with KG Plummer Block Housings, for use under normal operating conditions. For more information on use of special seals, please contact KG International FZCO.
Special types can also be developed to meet specific requirements. Technical information for such special Plummer Blocks, which do not appear in our regular production program can be made available whenever required.
