Graco 114548 Bronze Bearing
The Graco 114548 Bronze Bearing is a precision component designed to ensure smooth operation and pivoting in Graco line striping machines. It helps the detent arm pivot over the shoulder bolt, maintaining reliable engagement of the stop wedge.

Key Features
- Made from durable bronze for wear resistance
- Enables smooth pivoting of the detent arm
- Helps maintain proper alignment and reliable operation of the stop wedge
- Easy to replace — two required per detent arm
Where It’s Used
This bearing is installed in the **193528 arm detent** assembly, which guides the stop wedge into and out of the disk adjuster when the front wheel trigger is pulled. :contentReference[oaicite:4]{index=4}
Why It Wears Out
Over time, the bronze bearing can wear due to repeated pivoting and mechanical stress. Worn bearings may cause the detent arm to misalign, resulting in poor engagement of the stop wedge and less smooth operation. :contentReference[oaicite:5]{index=5}
Replacement Advice
- Always use genuine Graco 114548 bearings to maintain performance.
- Replace both bearings in the detent arm at once for balanced wear.
- After installing, pivot the arm manually to ensure smooth motion.
- Consult your machine’s manual before ordering to verify part compatibility. :contentReference[oaicite:6]{index=6}
Installation Notes
- Disassemble the detent-arm/sholder bolt assembly carefully.
- Remove the old bearings and clean the seat thoroughly.
- Press in the new bronze bearings gently (do not hammer aggressively).
- Reassemble and test the pivot by hand to ensure free motion.
When the bearing wears, the detent arm may not pivot correctly. This misalignment can prevent the stop wedge from engaging or releasing smoothly, reducing performance and potentially causing mechanical stress elsewhere. :contentReference[oaicite:7]{index=7}
You need **two** 114548 bronze bearings for each detent arm assembly. This is consistent across the supported LineLazer IV and V models. :contentReference[oaicite:8]{index=8}
It's strongly recommended to use the genuine **bronze** bearing (i.e., part 114548). Bronze offers the right combination of hardness and low friction for the detent arm’s pivot point. Using other materials may lead to faster wear or improper operation.
