Multiquip 11150 Bearing Insert .50 I.D. - OEM Replacement Part for Trowels

This bearing insert (bronze bushing) fits inside the spider plate and serves as the critical wear surface between the trowel arm and spider plate connection on Multiquip walk-behind power trowels. The .50 inch inside diameter bearing ensures smooth rotation of the trowel arm assembly during concrete finishing operations.

During trowel arm maintenance, these bronze bushings should be carefully removed from either the trowel arm or spider plate after removing the hex head bolt (Zerk fitting) and roll pin. Inspect bushings for wear or damage and replace if cleaning does not restore proper function. Damaged or worn bearing inserts can cause erratic blade rotation and prevent the smooth, fluid motion required for quality concrete finishing. The bushings can become dislodged during trowel arm removal or may require replacement after rough handling incidents such as dropping the trowel or striking exposed plumbing, forms, or rebar during operation.

This bearing insert is compatible with the following Multiquip power trowel models:

• EHHNK5
• HHN-34TVD
• HHNG4
• HTN27KTCSL
• HTNS5S-2
