Rimtec Corporation - Keyless Clamping


Keyless Clamping

Keyless clamping products protect high-torque applications using a design that offers easy shaft/hub assembly and removal that eliminates the need for expensive close-tolerance fits, milling work and multiple splining. In addition, keyless clamping reduces the risk of failure of keys due to stress concentration, corrosion, pitting and fatigue due to cyclical loading and unloading.

The line transmits torque up to 1.5 million ft-lbs (2.0 million Nm) for shaft diameters 1/4" (6 mm) to exceeding 40" (1000 mm).

Benefits/features include:

	Highly protective locking pressure during high-torque transmission
	"Shrink" design allows for slippage if preset torque is exceeded
	Keyless locks "squeeze" shafts to gears or shafts
	Uniform loading
	No stress concentration
	Reduces tooling and manufacturing costs
	Reduces risk of failure of connection between shaft and mating part
	Enables true-angle adjustment and axial positioning at any point of the shaft
	Locking pressure maintained indefinitely, with no deformation of shafts or gears
	Ease of assembly and disassembly
	Custom sizes available for your special needs
	Ease of adaptation for design modifications of shafts and hubs/gears.

Multiple keyless clamping products are available:
