Description
P7-S is a unique patented type of tension bushing which, unlike other tension bushings, closes completely at the slit (gap). Thereby, P7 S can replace most turned steel bushings at a lower cost. The closed slit enables the lubrication to remain inside the bearing, generating fewer maintenance periods. P7-S is an excellent universal bushing suitable for all kinds of applications where heavy loads, grinding and abrasive movements or big shock stress occurs.
Material
P7 S are made of boron-alloyed steel (37MnB4) which is a material with exceptional abrasion resistance. The steel is tempered to between 44-54 HRc, depending on the heat treatment method. After hardening, the material has a very fine-grain structure which makes it easy to machine.
Lubrication
P7-S needs lubrication for optimal lifespan and performance. All common greases or oils can be used. The bearings are surface treated with MoS2 providing protection against corrosion while it also serves as initial lubricant during start-up process.
