PNA15/32 Needle Roller Insert Type Bearing No Sealed Temperature –20 °C to +100 °C

1. Product Overview

PNA15/32 is metric PNA series self-aligning split adjustable eccentric needle roller bearing equipped with complete integral inner ring, unified standard dimension inner bore d=15mm, outer diameter D=32mm, overall width B=16mm. Unique spherical outer ring plus split outer sleeve structure realizes static misalignment compensation and tiny center distance fine adjustment during installation, effectively eliminate assembly deviation error between shaft and housing holes.

Pre-assembled unit includes precision cylindrical needle rollers, stamped steel retainer and quenched solid inner ring, split outer sleeve with reserved tightening gap, lock adjusted position via bolt compression after positioning. All rings and needle rollers adopt through-hardened GCr15 bearing steel with ultra-precision grinding, strictly sorted rollers for consistent dimensional tolerance, stable low-noise rotation under medium alternating radial load. Widely applied to printing machine tension rollers, automatic packaging film unwinding shafts, light material conveyor support rollers and textile auxiliary rotary positioning assembliesSKF 集....

3. Core Advantages

1. Spherical outer ring self-aligning + split sleeve adjustable dual design, perfectly compensate machining and assembly misalignment of shaft and housing, reduce equipment assembly reject rate.
2. Integral quenched inner ring as standard configuration, no extra heat treatment and grinding for matching shaft, simplify spare part processing and shorten assembly cycle.
3. Ultra-thin radial cross-section layout, occupy minimal radial installation space, ideal matching solution for narrow roller support structure of printing and packaging light machinery.
4. Mirror superfinished needle rollers with strict diameter sorting, uniform load distribution on each roller, low running noise and small temperature rise under long medium-speed continuous operation.
5. Split outer sleeve with compression gap, firmly lock adjusted eccentric position after tightening, no position shifting during long-term equipment running.
6. Full customizable service support: C3 enlarged radial clearance, P6 high precision grade, OEM laser marking on outer sleeve, neutral export carton anti-rust packaging.
7. One-piece pre-assembled bearing unit, steel cage fix needle rollers tightly, avoid roller scattering during disassembly and after-sales maintenance.
8. Outer sleeve surface passivation anti-corrosion treatment, stable rust resistance for indoor light dust industrial working environment.
