Standards and Tolerances.

Our machinery, and the machinery of our suppliers, limits us to maximum and minimum sizes leading to tolerances in AL,RL,LOB,SWL,LOM and LOT sizes.

Tolerances

Cut Spindles and tubing : = +0.0 mm / -0.5 mm

Plastic labyrinth seal and bearing cartridges : = +/-0.05 mm

Deep drawn and/or turned steel bearing : = +0.0 mm / -0.2 mm

Precision Bearings : = negligible 

Pressed and turned conical bearings ; = +0.0 mm / -0.3 mm

AL = Spindle Length
FM = Frame Size
IL = Enclosed Length
