Product FAQs
What do No.1 and No.2 bush mean?
Biloc pulleys use two bush series. No.1 bushes fit Biloc pulleys from 71mm to 132mm diameter, while No.2 bushes fit Biloc pulleys from 140mm to 450mm diameter. Once the correct bush series is identified, select the bore size to suit your shaft.
Why is the bush sold separately?
Biloc pulleys use interchangeable bushes so the same pulley can be fitted to different shaft sizes. This reduces inventory requirements and makes future shaft changes or pulley reuse much easier. A standard single-pulley assembly requires a Biloc bush and retainer kit. If joining two pulleys together to create a double groove assembly, use the appropriate No.1 long bolt set or No.2 long bolt set instead of a retainer.
Do I need a keyway?
No. Biloc bushes use a keyless locking system that securely grips the shaft without requiring keys or grub screws.
What is a Biloc retainer kit?
A retainer kit secures a single Biloc pulley to the bush assembly.

Do I need a retainer kit?
