Learn what h6 and h7 shaft tolerances mean, how shaft diameter affects linear bearing clearance, and why the housing bore must also be checked.

Learn how to calculate linear guide rail length from the required stroke, block length, block spacing, end margins and mounting-hole arrangement.

Learn how to estimate linear guide running resistance from applied load, friction coefficient, seals and preload, then include it in actuator or ball

Calculate ball screw thermal growth from screw length and temperature rise, then compare compensation methods for fixed-supported and fixed-fixed feed

Learn how the screw shaft, ball nut, support bearings and mounting structure combine to determine ball screw axial stiffness and elastic positioning e

Learn how roll, pitch and yaw moments affect linear guide load distribution and how to estimate the most heavily loaded block in a dual-rail, four-blo

Learn how to calculate ball screw positioning resolution and understand how screw lead, encoder counts and transmission ratio affect the theoretical l

Ball screw starting torque and running torque describe different operating conditions. Starting torque must initiate rotation and accelerate the axis,

The main difference between open and closed linear bearings is not simply the shape of the bearing shell. It determines whether the bearing can travel

When a machine requires a travel length beyond the practical manufacturing or shipping length of a single linear guide rail, several matched rail sect

Calculating ball screw motor torque requires more than converting the moving load into an axial force. A reliable estimate should also consider accele

SK and SHF linear shaft supports both secure the ends of round linear shafts, but their mounting structures are different. SK supports mount from the
