The Husqvarna 502563301 PG530 Bottom Bearing Circlip 64mm is a genuine OEM replacement component designed for the DM1PACE, DM280, DM340, DM650, and DM700 PRIME concrete core drills. As a direct OEM part, it matches the original circlip specification exactly, ensuring the bearing assembly seats and retains correctly within the drill motor housing. DHS Equipment supplies this part to help keep your core drilling equipment running at full capacity.
Key Features
- Precise OEM Circlip Geometry — Manufactured to Husqvarna's exact 64mm diameter specification, ensuring correct snap engagement and bearing retention without distortion or play.
- Direct Drop-In Replacement — Slots into the bottom bearing position of the drill motor assembly the same way as the original, requiring no modification to the housing or bearing bore.
- Broad Core Drill Compatibility — Confirmed fitment for the DM1PACE, DM280, DM340, and DM650 concrete core drills, as well as the DM700 PRIME equipment, covering a wide range of Husqvarna's professional drilling lineup.
- Bearing Position Integrity — A correctly seated circlip keeps the bottom bearing locked axially in place, preventing drift or wobble that can accelerate wear on the spindle and surrounding components.
- Genuine Husqvarna OEM Part — Sourced directly from Husqvarna's construction equipment parts catalog, cross-reference 502563301 against your parts diagram to confirm fitment before ordering.
A circlip — also called a retaining ring — is a small but critical fastening component that sits in a machined groove to lock a bearing in its axial position within the drill motor housing. In a core drill motor, the bottom bearing circlip prevents the spindle bearing from shifting under the rotational and downward load forces generated during drilling. When this clip becomes deformed, corroded, or dislodged, the bearing can migrate out of position, leading to uneven spindle loading, increased vibration, and accelerated wear on both the bearing and the motor housing. Replacing a worn or failed circlip promptly restores proper bearing retention and protects the surrounding drill motor components from secondary damage.
