RIMEX offers a wide-range of one-piece, two-piece, and articulating lock rings manufactured to the highest standards using quality steel.

One-piece Lock Rings

One-piece lock rings are produced with a minimum 2″ overlap (exact amount will vary slightly by size and type). Over time lock rings will lose their spring and the amount of overlap will reduce. Therefore, RIMEX recommends regular visual inspections of the lock ring to ensure it hasn’t stretched beyond product guidelines. Read about lock ring inspection and safety.

Articulating Lock Rings (ALR)

RIMEX articulating locks rings are designed to increase safety. Unlike traditional one-piece lock rings, there is no stored energy released when the part is removed. Damaged hinges are easily replaced and do not result in a scrapped component. Optional EZ GRIP handles protect hands from the hazards and dangers associated with with tire maintenance.

ALR Advantages

• Easy to install
• Identical lock ring halves hinge from either end to suit the wheel position.
• All components are recessed reducing the risk of damage during operation.
• Damaged ALR hinge assemblies are easily replaced as needed.
• The lock ring style is clearly engraved beside the hinge on each section of the ALR, for easy identification.
• No overlapping ends, eliminating  pinchpoint injuries.

RIMEX manufactures Articulating Lock Rings for 51 – 63″ lock ring styles (HDT, TSR, MST) to suit all equipment types.

Two-piece Lock Rings

RIMEX produces two-piece lock rings for DGS and IGLR style wheels.

Safety benefits of 2 piece lock rings:

• Pinch points and unreleased tension, eliminated
• Lock ring sections are lighter, easier to handle, install and secure in place
• The sections are bolted together with retaining clamps ensuring they remain secured in place
• Easy to store

Quick Reference Lock Ring Comparison

The images below demonstrate the differences between common 51-63” lock ring styles. The larger surface area of the TSR product offers a better fit between lock ring taper and bead seat band taper.

Using fully machined RIMEX components results in decreased movement and indexing of rim parts and consequently increased product strength and longer service life.

Style
HDT
WTR (Wedge)		37% more surface area than HDT
TSR		57% MORE surface area than HDT; 20% MORE surface area than WTR

Single Piece Lock Ring Safety

20” – 63” [EM, EMH, HDT, TSR, MS/T]

CORRECT OVERLAP	STRETCHED	SCRAP
2″ overlap	minimal overlap or ends touching	no overlap – ends NOT touching

20” – 49” [EV/T]

CORRECT OVERLAP	STRETCHED	SCRAP
2″ overlap	minimal overlap or ends touching	no overlap – ends NOT touching

New lock rings are produced with a minimum 2” overlap from the factory (exact amount will vary slightly by size and type).

Over time lock rings will lose their spring and the amount of overlap will reduce. This is a normal occurrence. Regular visual inspections of the lock rings need to be performed to ensure they haven’t stretched beyond the recommended guidelines.

RIMEX recommends that once the ends of a lock ring are no longer overlapped or touching, it should be removed from service and scrapped.

This stretched lock ring has just been removed from a wheel. It should be removed from service and scrapped.
