⚙️Product Description:
Dealing with macroscopic engineering that demands a massive 50mm rotational axis within a restricted envelope? The 6810-2RS and 6810ZZ Thin Section Bearings (50x65x7mm) represent a breakthrough in large-scale structural design. By offering a mega-bore of 50mm constrained within a remarkably slim 7mm width and 65mm outer diameter, this bearing provides an expansive central conduit for heavy hydraulic bundles, complex power cables, and central support pillars. It is the structural backbone for industrial robotic base joints and large-format indexing tables. As a premier B2B bearing trading enterprise, we deliver dual-tier procurement excellence: drastically reduce your heavy-machinery BOM costs with our rigorously tested RMO brand, or utilize our global channels to source specific tier-1 international legacy brands for your uncompromising heavy-industry audits.
⚙️Product Features:
- 50mm Mega-Bore Architecture: The extraordinarily large internal diameter unlocks unprecedented routing capabilities for multi-channel slip rings and massive drive shafts, essential for large-scale automation.
- Industrial-Grade Shielding: Deploy the 6810ZZ (Metal Shields) for large, high-speed textile rollers needing maximum heat dissipation, or the 6810-2RS (Rubber Seals) to lock out metal shavings and heavy dust in harsh CNC milling centers.
- Sectional Load Distribution: Despite the thin 7mm profile, the massive 65mm circumference accommodates a high volume of rolling elements, evenly distributing heavy axial and radial loads across a wider plane.
- Thermal & Dimensional Stability: Crafted from high-grade 52100 (GCr15) chrome steel and precision-ground to prevent the warping and deformation that commonly affect large-diameter thin bearings under thermal stress.
- Agile B2B Sourcing Paradigm: Seamlessly scale your production. Order bulk pallets of our highly competitive RMO brand for commercial equipment, or specify premium global brands for aerospace and defense-grade applications.
⚙️Product Application:
Bridging massive rotational needs with space-saving geometry, the 6810 series is indispensable in macro-scale applications:
- Main base joints and rotating pedestals for heavy-payload multi-axis industrial robots.
- Large industrial rotary index tables, slewing drives, and precision turntables.
- Astronomical telescopes, radar gimbal bases, and large-format optical tracking mounts.
- Heavy textile weaving looms, industrial printing press rollers, and large fluid pumps.
- B2B heavy machinery OEMs, defense contractors, and specialized industrial component importers.
⚙️Precautions:
| 1. Keep clean | 2. Use with caution | 3. appropriate tool | 4. Hot-loading | 5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
