H3130 ISB adapter sleeve

ISB H3130 Adapter Sleeve (Complete Assembly Kit)

The ISB H3130 is a comprehensive mounting system designed to secure bearings with a tapered bore (1:12 taper) onto smooth cylindrical shafts. This adapter sleeve is a vital component in heavy engineering, allowing for the installation of large spherical roller bearings without the need for expensive tapered shaft machining. The kit includes a slotted steel sleeve, a lock nut, and a tabbed lock washer that prevents the assembly from loosening during operation.

Application

• Heavy-duty Spherical Roller Bearings: Mounting 23130 K series bearings onto 135 mm shafts.
• Conveyors and Crushers: Secure fastening of drive drums in harsh operating environments.
• Paper and Textile Machinery: Precise seating of wide rollers on cylindrical shafts.
• High-power Industrial Fans: Vibration elimination through perfectly centric shaft clamping.
• Ball Mills and Mixers: Resistance to high dynamic loads and mechanical shocks.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: H3130
• Kit Components: Sleeve (H 3130), Nut (KM 30), Washer (MB 30).
• Taper ratio: 1:12 (Industry standard).
• Material: High-yield strength structural steel.

Note: The H3130 sleeve is designed for a shaft diameter of 135 mm (d1 dimension).

Features and Benefits

• Manufacturing Cost Reduction: Allows the use of cost-effective smooth drawn shafts instead of stepped shafts.
• Precise Clearance Adjustment: Tightening the nut allows the bearing to be pressed onto the taper, accurately setting its internal radial clearance.
• Secure Locking System: The MB washer permanently locks the nut, eliminating the risk of loosening due to machine vibration.
• Streamlined Maintenance: The sleeve design facilitates easy bearing removal during scheduled replacements.
• High Load Capacity: The H3130 series is engineered to withstand extreme pressures in heavy-duty bearing nodes.

Why Choose This Product

The ISB H3130 adapter sleeve is a guarantee of safety for large-scale bearing installations. By adhering to ISB's rigorous production standards, the threads are resistant to stripping even when using hydraulic mounting tools. Choosing this product ensures that the bearing remains fixed in its designated position, drastically reducing the risk of shaft damage and unscheduled production downtime.
