NNF5010ADA-2LSV Double Row Full Complement Cylindrical Roller Bearing 50×80×40mm Double Sealed Locating Bearing

1. Product Overview

The NNF5010ADA-2LSV is double row full complement cylindrical roller locating bearing without cage, fitted with double integrated 2LS contact rubber seals and built-in relubrication channel. Split inner ring with three ribs and outer ring with single central rib realize bidirectional axial positioning to fix shaft position firmly. Full roller layout maximizes rolling elements quantity for ultra-high radial load capacity and high rigidity. Double-sided 2LS rubber seals block dust, water mist and debris to protect internal grease, matching damp, dusty industrial environments. It bears heavy combined radial load and bidirectional axial load simultaneously, widely used as fixed-end bearing for wire winding machines, heavy gear reducers, lifting equipment and compact heavy-duty transmission assemblies.

3. Key Advantages

• Cage-free full complement roller design holds maximum rollers, greatly improves radial load capacity and structural rigidity for heavy shock and vibration working conditions
• NNF locating structure with three inner ribs and central outer rib limits bidirectional shaft axial displacement, no extra stop rings required for assembly
• Double-sided 2LS integrated contact rubber seals provide excellent dustproof and waterproof performance, avoid grease leakage and extend maintenance cycle
• Built-in outer ring lubrication channel supports on-site re-lubrication without disassembly, suitable for long-time continuous operation equipment
• Two snap ring grooves on outer ring simplify axial installation and save housing internal space for compact machinery design
• Customizable options include open non-sealed version, C3 enlarged clearance, OEM laser marking and special high-temperature anti-wear grease
• Effectively reduce equipment axial positioning parts cost and lower long-term maintenance downtime

4. Applications

This bearing is widely matched for the following compact heavy industrial equipment:

• Copper/aluminum wire winding machine main rotary fixed support shafts
