Trapezoidal thread design. Use with metric leadscrew thread listed in separate category.
Material: KSM = Carbon Manganese Steel S300 Pb (11 SMn Pb37) / LRM = Bronze CuSn8P. Carbon Manganese steel can be welded but difficulties may arise with bubbling due to sulphur content. KSM: Manual control control only - low rotational speeds only - for clamping or locking functions - for receiving dead weights. LRM: Manual or powered control - low and medium rotational speeds - for working under load. For power transmission and continuous use always use bronze nuts not steel.

Bearings and Spare Parts
Where alternative parts are offered, we make no claims as to their suitability. Selection of the most suitable bearings and parts is the responsibility of the customer. We recommend you replace bearings with the same type if that type is working well. High speed caged bearings are better suited to handle vibration than standard caged bearings.
