Great fitment and quality

ID 38mm matched our shafts perfectly. Very durable brass material. Would recommend for industrial machinery upgrades.

Good value for money

Solid brass construction works well under stress. Shipping took a bit longer than expected but the product quality makes up for it.

Perfect for high load applications

Installed these on our hydraulic press last month. The graphite infusion really works, no lubrication needed so far and performance is stable.
