7230‑B‑XL‑MP‑UA Angular Contact Ball Bearing 150x270x45mm for Gearbox Shaft Compressor
Product Overview
- 7230‑B‑XL‑MP‑UA is open‑type single‑row angular contact ball bearing with 40‑degree contact angle and machined brass cage.
- UA universal match design allows direct pairing for DB, DF or DT mounting without extra spacer adjustment.
- It handles combined radial load plus heavy one‑way axial load for heavy‑duty transmission equipment.
- XL improved structure brings better load performance, solid brass cage stays stable under continuous heavy running.
- Open construction, users need to apply grease or oil lubrication while assembling on site.
