Flanged Hollow Shaft Bushing Guide Sleeve

Product Brief :

As Qimao Metal Manufacturer Flanged Hollow Shaft Bushing Guide Sleeve, this flanged bushing addresses both by holding H7 bore tolerance with a Ra 0.8 ground finish, keeping the shaft centered and reducing friction-related wear. The flange eliminates the need for retaining rings and stops axial creep under load – a simple but effective design we’ve used across hydraulics, press tooling, and automation slides.

Material selection is application-driven: SAE 660 bronze for general wear resistance, 4140 steel for impact-heavy setups, 316 stainless when corrosion resistance is the priority. We can cut oil grooves straight or helical to suit your lubrication interval. Lead time 3-7 days on custom orders – just send your drawing and operating conditions.

Product Details

Flanged Hollow Shaft Bushing Guide Sleeve as a real‑source cold heading factory, we handle the whole workflow from raw material cutting, and deal with customer require ,such as surface treatment and the specification , turning to post‑surface treatment in‑house. Our team reads customer mechanical drawings directly and gives practical manufacturability feedback before formal production. We manage small‑batch prototype orders as well as mass serial production. Full inspection records, material certificates are available upon request. We adjust cost‑effective solutions according to your actual working environment rather than over‑engineering every component blindly.Welcome contact us, only advise the item artwork, or send samples to us, we’ll feedback to you immediately.

Key Features:

1-Flanged Hollow Shaft Bushing Guide Sleeve for bore tolerance held to H7 with Ra 0.8 finish – keeps the shaft running true without slop, and the smooth bore cuts down friction so you don’t burn through bushings as fast

2-Flange does double duty – acts as a positive stop when you press it in, so you can skip the retaining ring, and it won’t walk out on you under vibration or side load

3-Materials matched to what you’re running – SAE 660 bronze for general wear, 4140 steel when you’re dealing with heavy impact, 316 stainless if moisture or chemicals are in play – we’ll spec it based on your conditions

4-We can tweak it to your print – oil grooves straight or helical, special coatings if you need them, non-standard bores or ODs – just send the drawing

Use Cases:

1-Hydraulic cylinders with FFlanged Hollow Shaft Bushing Guide Sleeve – piston rod guides where keeping things aligned means seals last longer and you don’t get bypass leaking

2-Press tooling and CNC machines – guide pillars and linear rails where you can’t afford slop or thermal growth throwing off your tolerances

3-Automotive and ag equipment – transmission rails, pivot joints, loader linkages – dusty, dirty, sees shock loading, needs something that holds up

4-Pumps and compressors – shaft supports in vertical pumps and reciprocating setups where you need concentricity and low friction

5-Field service replacements – we can match your worn bushing dimensions and upgrade the material or finish while we’re at it, no need to re-engineer the whole assembly
