PMI MSA Series Heavy Load Type

Features

The trains of balls are designed to a contact angle of 45° which enables it to bear an equal load in radial, reversed radial

and lateral directions. Therefore, it can be applied in any installation direction. Furthermore, MSA series can achieve a well balanced preload for increasing rigidity in four directions while keeping a low frictional resistance. This is especially suit to

high precision and high rigidity required motion.
The patent design of lubrication route makes the lubricant evenly distribute in each circulation loop. Therefore, the optimum lubrication can be achieved in any installation direction, and this promotes the performance in running accuracy, service life,

and reliability.

Characteristics

High Rigidity, Four-way Equal Load
Self Alignment Capability
Smooth Movement with Low Noise
Interchangeability

Dimension

MSA-A	MSA-LA	MSA-E

Installed from top side of carriage with the thread length longer than MSA-E type.	All dimensions are same as MSA-A except the length is longer, which makes it more rigid.	This type offers the installation either from top or bottom side of carriage.
MSA-LE	MSA-S	MSA-LS

All dimensions are same as MSA-E except the length is longer, which makes it more rigid.	Square type with smaller width and can be installed from top side of carriage.vvh	All dimensions are same as MSA-S except the length is longer, which makes it more rigid.
