Track roller for ring slides and rotary tables

RING SLIDE ROLLERS · FV30 TYPE

Ring Slide Track Rollers (FV30 Type)

Ring slides and circular production lines move carriers around a closed track. Track rollers on the inner and outer edges of the ring guide the carriers. Our ring slide rollers are the FV30 type. There is no standard size list: we make each roller to the ring and carriage drawing.

Typical applications: rotary indexing tables, circular assembly lines for batteries and medical parts, curved guide tracks.

What to send for a quote

Ring slide rollers are sized to the ring. Send the items below, or a drawing of the ring and carriage.

Item	Why we need it
Ring diameter and edge profile (V-groove angle or gothic arch)	The roller profile must match the ring edge, and contact must stay centred on the profile.
Roller OD, width and stud size, or an old roller	The roller must fit the existing carriage and mounting holes.
Concentric or eccentric, and how many of each	Concentric rollers locate the carriage. Eccentric rollers take out play.
Load, speed and stops per minute	These set the bearing size, seals and accuracy.
Accuracy requirement	Roller runout and profile accuracy are agreed per drawing.

We do not publish standard sizes for ring slide rollers. Each order follows the customer drawing.

Selection checks for ring slide rollers

Match the roller profile to the ring edge first. A V-groove or gothic-arch roller must touch the ring on its profile, not on the edge.
Use concentric rollers on one side of the ring as the reference and eccentric rollers on the other side to remove play.
Design the carriage geometry for the ring radius. Otherwise preload changes when the carriage moves between straight and curved sections.
Hold the eccentric stud while you tighten the nut. Otherwise the setting moves.

Made to drawing

Send the ring and carriage drawing, or an old roller. We confirm profile, stud, eccentricity, seals and accuracy before we quote.

Frequently asked questions

What is the difference between a concentric and an eccentric roller?

A concentric roller sets the fixed datum. An eccentric mounting element is used to adjust system clearance or preload.

Do you have standard ring slide roller sizes?

No. We make ring slide rollers to the ring diameter and carriage drawing. Send the drawing or an old roller.

What is an FV30 type roller?

It is the roller style we make for ring slides: a track roller on a stud, in concentric and eccentric versions, with the outer profile made to suit the ring edge.
