1. Adapter Sleeve (H) --
Adapter sleeves are the quintessential components for securely mounting bearings with a tapered bore onto cylindrical shaft seatings. They can be utilized on both smooth and stepped shafts, ensuring a versatile and streamlined setup. These sleeves are renowned for their ease of installation, requiring no additional fixation on the shaft. When used on smooth shafts, the bearing can be positioned at any point along the shaft. EESCO adapter sleeves are delivered with a complete set, including a lock nut and a locking device for optimal security and performance.

2. Adapter Sleeve for Oil Injection (OH) --
These advanced sleeves feature oil supply ducts at the threaded end and distributor grooves in both the bore and the outer surface. Sizes up to 40 have a single oil supply duct, while larger sleeves are equipped with two, ensuring efficient lubrication and maintenance.

3. Withdrawal Sleeve (AH) --
Withdrawal sleeves facilitate the mounting of bearings with a tapered bore onto cylindrical seatings of stepped shafts. The sleeve is inserted into the bearing bore, pressing against a shaft shoulder or an equivalent fixed component. It is secured on the shaft by a nut or an end plate, with the sleeve itself being slotted and featuring an external taper of either 1:12 or 1:30, ensuring a reliable and robust fit.

4. Withdrawal Sleeves for Oil Injection (AOH) --
These AOH sleeves are engineered with dual oil supply ducts at the threaded end, along with distributor grooves running circumferentially and axially on both the outer surface and the sleeve bore. When oil is injected through these ducts and grooves, it forms a lubricating film between the mating surfaces of the bearing and sleeve, as well as between the shaft and sleeve. This dramatically reduces the force required for bearing installation, ensuring a smooth and efficient assembly process.

Application

Comprehensive Adapter Sleeve Applications
1. The adapter sleeve is ingeniously designed to secure conic aperture self-aligning ball bearings (including self-aligning ball bearings and self-aligning roller bearings) onto non-bearing shoulder bearings. Its simple structure ensures reliable performance and facilitates easy bearing replacement.
2. This product finds extensive applications across diverse industries such as textile manufacturing, light industry, metallurgy, belt conveyance, and various transmission equipment. Its versatility and dependability make it a crucial component in these fields.
