Amount of interference or clearance between bearing inside diameter and shaft bearing seat outside diameter.
Industry:Machine tools
The resistance to indentation. At minimum, it should be Rockwell C45.
Industry:Machine tools
Uniform radial deviation of the shaft surface. An oval shaft is said to have two lobes. Faulty centerless grinding usually causes an odd number of lobes to occur. Higher order lobing is also referred to as chatter.
Industry:Machine tools
Measurable irregularity or out-of-roundness in a rotating assembly, at a right angle to an axis.
Industry:Machine tools
A rolling element bearing designed primarily to support a load perpendicular to the shaft axis.
Industry:Machine tools
L10 of group of apparently identical bearings is the life in millions of revolutions that 90% of the group will complete or exceed.
Industry:Machine tools
Roller with slight modification of diameter at ends of outside surface to reduce stress concentration at contacts between rollers and raceways.
Industry:Machine tools
In seals, a long, narrow projection that is normally triangular in the cross section. It is molded into the outside lip surface of a helix seal. The rib is oriented at an angle to the shaft axis. One end of the rib forms part of the seal-lip contact surface. In tapered roller bearings, it is a raised structure at the end of the raceway that guides or supports the rollers.
