GQZ LRT2026-1 Precision Superfinished Needle Roller Inner Ring 20×25×26.5mm For Compact Transmission Mechanisms

LRT2026-1 is standard metric high-precision ground inner ring of IKO LRT series, perfectly matched with TAF192720 needle roller bearing. It serves as independent wear-resistant rolling raceway when the mating shaft cannot reach HRC60 hardness and mirror grinding finish. Fully quenched + double-pass superfinishing rolling surface delivers low friction and long service life, widely paired with TAF, TR, NK series inner-ring-free needle bearings for narrow-space compact rotary equipment.

1. High-hardness integral ground raceway solves shaft heat treatment and finish unqualified problems, save shaft machining cost
2. Standard interchangeable size with original IKO LRT2026-1, fully dimension compatible with TAF192720 needle roller unit
3. Ultra-slim thin-wall design minimizes radial occupied space, ideal for miniaturized mechanical layout
4. Double-end small chamfer relief reduces assembly friction, convenient for quick mounting and disassembly
5. Superfinished rolling surface cuts vibration, noise and heat generation during continuous high-speed rotation
6. Can be used separately as wear-resistant sliding bushing without matching needle rollers
7. Custom stainless steel inner rings, OEM laser marking and P6/P5 ultra-precision grinding tolerance supported
