Description
Overview:
Guide Sleeve B (Makita part number 331639-1) is a genuine Makita OEM component for JR/BJR series reciprocating saws, including BJR181 and BJR240. This precision-machined metal sleeve supports and aligns the reciprocating mechanism, helping the blade stroke run true and reducing lateral play. Correct alignment is important for clean, accurate cuts and for lowering wear on related parts such as the rod, blade clamp, and bearings. Replacing a worn guide sleeve can reduce vibration, improve cut quality, and restore tool efficiency. Designed specifically for Makita reciprocating (sabre) saws, it offers reliable fitment and long service life when installed and maintained correctly.
Key Features:
- Genuine Makita OEM part for assured fit and reliability (331639-1)
- Helps maintain precise blade stroke alignment for cleaner, straighter cuts
- Durable metal construction engineered for heavy-duty, repetitive use
- Direct-fit for listed JR/BJR series models to simplify selection
- Straightforward to install with basic hand tools during routine maintenance
- Can reduce wobble and vibration caused by a worn sleeve
- Supports smoother operation and helps minimise premature wear on mating parts
- Suitable as a like-for-like replacement when servicing the reciprocating mechanism
Typical Applications:
For use in Makita reciprocating saws used on site or in the workshop for cutting timber, plastics, metals, and demolition materials. Ideal when the tool shows increased vibration, wandering cuts, or noticeable play in the blade stroke. Common in building, plumbing, electrical, landscaping, fabrication, and general maintenance tasks where accurate, controlled reciprocating cuts are required.
Also known as:
Guide bushing, saw sleeve, sleeve for reciprocating saw, guide tube, bushing sleeve, alignment sleeve, stroke guide. These alternative terms refer to the same function: guiding and supporting the reciprocating assembly to keep the blade path stable.
