Track Pins
Hardened steel pins joining adjacent track links, running inside bonded rubber bushes rather than on metal. Articulation is taken up in bush torsion, so in a healthy track the pin never actually rotates. SES holds the range as an authorised JK Fenner distributor, covering material Alloy steel, through or case hardened; surface Ground finish with corrosion protection; interface Bonded rubber bush, interference fit; systems Single-pin and double-pin tracks. Executions include single-pin track pins, double-pin track pins, pin and bush kits, end connector pins, among others. It is specified most often into base workshop track joint rebuilds and field track repair kits. Every part is genuine JK Fenner through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Track Pins in the parts of a plant where this particular duty actually occurs. In practice that means base workshop track joint rebuilds, field track repair kits, track pooling for armoured fleets, and equally armoured recovery vehicle track repair, new track build lines, reactivation after long outdoor storage. What links them is the duty rather than the machine name — function: Link-to-link joint carrying full track tension. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the JK Fenner range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Pins are being pressed into used links — Pin diameter matched to the measured bore condition, not the nominal figure. A nominal pin in a bell-mouthed bore never holds its interference and walks out. Track feels stiff to articulate after a rebuild — The specified pre-twist at assembly. Bushes built in without pre-load work through their whole range in one direction and shear early. Repairs are carried out in the field rather than the workshop — Hold pin, bush and press tooling as a matched kit. Improvised drifting damages the bond before the track ever leaves the leaguer. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Never re-use a pin that has been hammered out. The struck end is upset by a few hundredths, and it will not press cleanly into a new bush however sound the pin looks. Send the designation off the failed part and we will confirm the JK Fenner equivalent and stock position.
