Product Overview
The ZF Needle Bearing 75x83x40 mm W (Part No. 0735321529) is a critical internal component used within ZF Ecomid, ZF S6, and other series transmissions to support gears on the input and intermediate shafts. It features a full complement of long, thin rollers that provide excellent load distribution under high radial stress—making it ideal for heavy-duty transmission environments.
This precision-engineered bearing ensures minimal play between rotating components, reducing vibration, wear, and noise during gear engagement. It is commonly replaced during transmission overhauls, especially when inspecting gear alignment or replacing worn synchronizers and bushings.
Constructed from high-grade chrome steel with precise heat treatment and surface finish, this bearing delivers superior durability and performance under continuous load cycles. Its sealed design (where applicable) helps retain lubrication and prevent contamination ingress.
Compatible with various ZF AMT and manual gearboxes found in MAN, Scania, DAF, Volvo, Sinotruk, Foton, and other commercial vehicle platforms, this bearing is a must-have for professional workshops and fleet maintenance teams.
As a certified ZF parts supplier, we guarantee OEM specifications, traceability, and reliability—making us your preferred global ZF parts dealer for quality transmission components.

Installation Tip: Always clean the housing bore thoroughly before installing the needle bearing—use a non-abrasive solvent and check for scoring or ovality. Do not hammer directly on the bearing; use a proper press and sleeve to ensure even force across the outer ring. Align carefully to avoid tilting. Never spin the bearing dry—ensure adequate transmission oil lubrication before startup. After installation, rotate the shaft manually to confirm smooth movement without binding. Replace associated worn gears or shafts simultaneously for optimal performance. Recommended only for trained technicians performing ZF transmission overhauls.
