HK101412 / HK1012 / HK1012-RS / HK1012-2RS Drawn Cup Needle Roller Bearing With Seals 10*14*12mm

1. Product Overview

HK101412, HK1012, HK1012-RS and HK1012-2RS are metric single-row through open drawn cup needle roller bearings without inner ring, unified outer diameter D=14mm, roller assembly inner diameter Fw=10mm, differentiated by width, roller layout and sealing configuration. HK series adopts integrated one-piece stamped thin steel outer cup, directly pressed into housing interference hole without extra snap rings or positioning sleeves to simplify assembly work.

• HK1012: Standard 12mm width open type without rubber seal, excellent heat dissipation for clean dry indoor production environments;
• HK1012-RS: 12mm width single-lip NBR contact rubber seal on one end, blocks light dust and slight moisture for lightly polluted workshops;
• HK1012-2RS: 12mm width double-sided RS rubber seals on both ends, full dust & moisture isolation for harsh dusty humid working conditions;
• HK101412: 12mm width thickened dense needle roller layout, larger contact area to upgrade dynamic & static radial load capacity for medium heavy shock load equipment.

Stamped thin steel cage evenly separates dense needle rollers to realize ultra-high radial bearing capacity under ultra-narrow radial cross-section. Matching installation shaft surface must be quenched to HRC60–64 and mirror superfinished to act as inner raceway. This series only bears pure radial load, widely used for miniature gearboxes, handheld power tools, textile tension rollers, automation sliding components, micro hydraulic valves and light agricultural machinery transmission assemblies with strict radial space limits.

3. Key Advantages

1. Integral thin steel drawn cup press-fit installation design, directly pressed into housing interference hole without additional axial fixing parts, cut component quantity and assembly labor cost
2. Ultra-thin radial cross-section greatly reduces equipment radial occupied space, perfectly meets miniaturized compact transmission structural design demands
3. Four optional structural variants (open / single RS sealed / double 2RS sealed / thickened heavy-load) cover all mainstream working conditions: clean dry, slightly dusty, heavy humid dusty and medium heavy shock load environments
4. Dense needle roller arrangement provides outstanding radial rigidity and load capacity, stable continuous medium-speed operation under frequent start-stop alternating impact loads
5. Lightweight stamped steel cage ensures uniform roller guidance, low friction loss and efficient heat dissipation for long-cycle non-stop equipment operation
6. Customizable options include C3 enlarged radial clearance, stainless steel anti-rust drawn cup, OEM laser marking and high-temperature wear-resistant grease filling

Effectively simplify housing machining processes and extend service life of compact shaft-end transmission assemblies
