Rollring Traverse Units - Versatile Linear Motion Solutions
Rollring Traverse units find versatile applications wherever linear reciprocating motion is required. They offer automatic and instantaneous reversal for unidirectional rotation and constant-speed rotation of a shaft. An added advantage lies in the finely adjustable linear speed, attainable with a simple lever adjustment on the unit, accompanied by the flexibility of varying stroke lengths. The Traverse unit operates on a plain round, hardened shaft with a finely ground finish

New and Improved Traverse Units!
We're proud to present our enhanced design and a range of new models tailored to fit shafts of various diameters, including 10mm, 15mm, 16mm, 20mm, 22mm, 25mm, 30mm, 40mm, 50mm, 60mm, and 80mm. Explore our HT1, HT2, 4RR15, HT16, 4RR16, HT3, 4RR20, HT22, 4RR22, HT25, 4RR25, HT3N, 4RR30, 3RR40, HT4, 4RR40, HT5, 4RR50, HT6, 4RR60, HT8, and 4RR80 models.

We offer two distinct types of Rollring Traverse units: the HT and 3RR series with 3 Rolling rings, and the robust Heavy-Duty 4RR series with 4 Rolling rings.

The 4RR series boasts double the load-bearing capacity, enhancing its capabilities for demanding applications.

Applications:
Rollring Traverse units are ideal for any application requiring linear reciprocating motion, constant-speed unidirectional rotation of a plain shaft with variable linear speed, stroke length, and automatic instantaneous reversal.

Traverse units are used across various industries to fulfil a wide spectrum of linear motion requirements. They serve as indispensable tools for efficiently winding materials of diverse shapes and dimensions. They cater to a broad range of applications, from delicate fibre optic wires to robust heavy-gauge cables. Whether it's wires, ropes, flat materials, strips, straps, hoses, filaments, tapes, foils, or even solid materials such as steel, aluminium, copper, rubber, plastic, and fibre, Traverse units ensure precise and effective winding.

Side Thrust

The side thrust refers to the force that can be safely applied. If this force surpasses the specified maximum value, the traverse unit will slip on the shaft.

Pitch

The pitch signifies the linear displacement of the traverse unit for a single revolution of the shaft. The pitch reaches its maximum value when the dial is set to 10. To adjust the pitch with precision, the pointer lever is shifted along the dial. For optimal accuracy and performance, it's recommended to operate the traverse unit above setting 1 on the dial

Maximum Pitch

The maximum pitch represents the linear movement or one rotation of the shaft, typically set at dial setting 10.
