H317 ISB adapter sleeve

ISB H317 Adapter Sleeve (Complete Mounting Kit)

The ISB H317 is a complete mounting solution designed to secure bearings with a tapered bore onto plain or stepped cylindrical shafts. This adapter sleeve is the most widely used component for installing spherical roller bearings and self-aligning ball bearings. The kit includes the slotted steel sleeve, a lock nut (KM), and a lock washer (MB). As the nut is tightened, the sleeve is drawn into the bearing bore, compressing onto the shaft to create a secure, high-friction interference fit.

Application

• Spherical and Self-aligning Bearings: Mounting "K" series bearings (e.g., 22217 K) on cylindrical shafts.
• Industrial Fans: Stable rotor mounting on standard shafts without specialized machining.
• Conveyor Systems: Simplified maintenance procedures in heavy-duty material handling.
• Agricultural and Crushing Machinery: Resistance to vibration and impact due to a robust mechanical clamp.
• Transmission Shafting: Allows bearing placement anywhere along a long shaft without the need for shoulders.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: H317
• Components: Sleeve (H), Nut (KM 17), Washer (MB 17).
• Taper: 1:12 (Industry standard for K-series bearings).

Note: The H317 sleeve is designed for a shaft diameter of 75 mm (d1 dimension).

Features and Benefits

• No Specialized Machining: Eliminates the need for expensive tapered shaft machining, reducing production costs.
• Internal Clearance Adjustment: Allows for precise control of the bearing’s internal clearance during installation.
• Secure Locking: The MB washer tabs lock the nut into place, preventing loosening caused by machine vibration.
• Simple Disassembly: Quick removal process without damaging the shaft surface.
• ISO Standard Compliance: Full interchangeability with other premium adapter sleeve brands.
