Regal Rexnord couplings
Rexnord Rigid Couplings
Rexnord rigid couplings for fixed, non-flexible torque transmission between aligned shafts - Tollok TLK500 and 3000 Series MCF lines within Regal Rexnord.
Rexnord rigid coupling overview
Rexnord rigid couplings provide fixed shaft connections where flexible misalignment accommodation is not required. The Regal Rexnord portfolio includes Tollok TLK500 rigid couplings and 3000 Series MCF couplings for medium and large-drive applications.
Tollok TLK500
TLK500 is a Tollok rigid coupling line within the Rexnord rigid coupling portfolio, used where a fixed torque-transmitting connection is specified. Confirm bore, torque duty and mounting requirements against published TLK500 catalogue data.
3000 Series MCF
3000 Series MCF rigid couplings address large-drive shaft connection requirements within the Rexnord catalogue. Selection depends on application layout, bore and duty ratings per manufacturer tables.
When to specify rigid couplings
Rigid couplings suit applications with controlled alignment where a flexible element is not required. For misalignment accommodation, compare Lifelign gear, Omega elastomeric or other flexible families on the Rexnord couplings hub.
Engineering enquiry
Authorised Regal Rexnord distributor quotation support. Send bore, torque and application data.
Have a part number or designation?
Send manufacturer part numbers, bore sizes or coupling designations for engineering identification and quotation support. This is an identification/interchange enquiry—not a live stock lookup or availability confirmation.
Common questions
No. Rigid couplings require aligned shafts within manufacturer installation tolerances. Flexible coupling families should be used when significant misalignment is expected in service.
They are distinct product lines within the Rexnord rigid coupling portfolio with different size ranges and application focus. Send installed marking or duty data for model selection and quotation.
