Transmission replacement belts engineered to match PJ475 circumference and restore reliable drive performance, ideal for routine maintenance. Practical durability and clear rib markings reduce guesswork for workshop technicians and DIYers. Are these the right belts for your PJ475 application, and do they match required rib counts? Generic V-ribbed Belts
⚡ At a Glance
- • Rib Profile: Multiple V-ribbed profile provides friction and wedge advantages
- • Best for: Workshop maintenance and DIY repairs on small transmission drives
- • Not ideal for: High-torque industrial drives outside the stated PJ475 circumference range
PJ475 corresponds to a 475mm circumference with compatible 187J profiles. High-grade engineered rubber ensures consistent grip and wear resistance.
Reliable power transfer - thanks to multiple V-ribbed profile
Ribbed poly-V geometry increases contact area and combines wedge action with friction to transmit torque efficiently. The J-series rib counts clarify how load spreads across the belt surface.
More consistent engagement with pulleys reduces slipping and improves drive smoothness, especially during start-up and variable loads.
Durable performance - with high-grade engineered rubber
Formulated rubber resists abrasion and flex fatigue from repeated bending over pulley grooves. Reinforced construction helps preserve rib shape under typical operating cycles.
Longer service life lowers frequency of replacements, making maintenance intervals more predictable for workshops and hobbyists.
Simple sizing and fitment - thanks to PJ475 code and J-rib labelling
PJ475 is the metric code indicating a 475mm circumference, while J4, J5, J6 labels denote the number of ribs on each belt. Clear markings speed up correct part selection.
Quick identification reduces downtime during repairs and ensures correct matching to pulley widths and rib profiles.
