941/17 DB1714E Drawn Cup Full Complement Needle Roller Bearing 17×23×14 One Side Sealed

1. Product Overview

941/17 is standard GOST drawn cup full complement needle roller bearing, equivalent brand model DB1714E, unified metric dimension Fw17×D23×B14mm. Suffix E stands for single-side rubber contact seal integrated on the cup opening for dust and debris isolation.

Cage-free full needle layout fills maximum quantity of cylindrical needles inside thin stamped steel cup, achieving far higher radial load capacity than caged needle bearings under identical radial space. No independent inner ring matched; quenched and ground transmission shaft surface directly acts as inner rolling raceway to minimize equipment layout size. Thin deep drawn steel outer cup features high structural rigidity after heat treatment, integral flanges lock needle rollers to prevent axial slipping during reciprocating rotation. Single lip rubber seal blocks metal chips, dust and light splash impurities, retain internal pre-filled lubricating grease to extend maintenance interval. Widely applied to electric power tools, miniature gearboxes, textile winding machinery, small hydraulic valves and light automation compact transmission mechanisms. All steel cup and needle rollers adopt fully quenched GCr15 bearing steel with superfinished contact surface for stable wear resistance under continuous low-to-medium speed heavy radial load.

2. Technical Specifications

Complete power tool gearbox installation drawings, compact radial load matching guide and long-cycle dust-proof wear durability test reports can be provided upon customer request.

3. Core Advantages

• Cage-free full complement needle design, maximum rolling element filling quantity, ultra-high radial bearing capacity, perfect for miniature equipment with limited radial installation space.
• DB1714E single-side rubber sealing structure, effectively isolate workshop dust, fine metal debris and light splash, avoid grease loss and needle oxidation rust.
• Thin deep drawn integral steel cup, one-piece stamping forming without split structure, good roundness and deformation resistance after heat treatment.
• No independent inner ring structure, save extra inner ring assembly space, simplify equipment shaft layout and reduce overall component volume.
• Fully quenched needle rollers and steel cup reach HRC60–65 hardness, excellent anti-indentation and anti-fatigue performance, reduce frequent spare parts replacement of power tools.
• Ultra-smooth superfinished needle rolling surface, low friction coefficient, stable low-noise operation under long-time frequent forward-reverse rotation of power tool spindles.
• Dual standard interchangeability: 941/17 Russian GOST standard, DB1714E European brand standard, fully replaceable without modifying shaft and housing.
• Comprehensive customized service: P6 high precision upgrade, double-sided seal version conversion, OEM laser marking on outer cup surface, neutral export carton anti-rust packaging, high-temperature anti-wear lithium grease pre-filling.
