Find bearings by gearbox shaft
Input, intermediate and output shafts each carry different loads, so each needs a different bearing family. Cylindrical roller bearings suit floating positions on gearbox shafts. Tapered and angular contact bearings take combined radial and axial loads. Spherical roller bearings handle heavy shafts with misalignment.

Our gearbox rebuild shop uses Koyo tapered and cylindrical roller bearings from jpkoyo.com. Every bearing matches the JTEKT execution we specify, and our rebuilt gearboxes are running longer between overhauls.
★5.0 —— Giuseppe Romano
A conveyor gearbox failed at our plant and we needed Koyo spherical roller bearings urgently. They identified the correct Koyo reference, shipped the same day, and the gearbox was back in service within the week.
★4.9 —— Mahmoud Khalil
They understand gearbox bearing arrangements. When we submitted a mixed list with floating and locating positions, they confirmed which Koyo series fit each shaft before quoting. No wrong deliveries in a year of orders.
★5.0 —— Stefan Nowak
Bulk pricing on Koyo roller bearings for our gearbox assembly line was competitive, with genuine packaging and correct quantities. Delivery to our port arrived on the agreed date.
★4.9 —— Rodrigo Almeida
As a transmission repair workshop, we previously split Koyo orders across several suppliers. This one consolidates our lists, matches references accurately, and the bearings are always genuine JTEKT product.
★5.0 —— Willem Botha
The Koyo needle roller bearings and tapered bearings for our drive assembly were supplied exactly to specification. Our engineer checked the fit on arrival and installation went without modification.

Reference check before quoting
We confirm the full suffix, the shaft position and the required configuration first, so the bearing that arrives is the bearing that fits. Any technical change needs your approval.
01
A shortened stock code on a maintenance list drops the suffix that defines the original seal and internal clearance. We restore the full Koyo / JTEKT reference before quoting.
02
Repair lists often mix drive end and non-drive end, or floating and locating positions, under one line. We separate them by shaft so quantities and fits come out right.
03
When the equipment specification calls for a specific configuration, a bearing with the same bore and outside diameter can still be wrong. We check the configuration and the full assembly before quoting.
