6810-ZZ Thin Section Deep Groove Ball Bearing For High-Speed & Lightweight Assemblies | 50×65×7 mm

The 6810-ZZ is a precision single-row thin-section ball bearing from the 6800 (61800) series, equipped with non-contact pressed steel shields on both sides. Featuring a 50 mm bore diameter paired with an exceptionally slim 65 mm outer diameter and 7 mm width, this bearing is engineered to provide reliable radial and axial support while significantly reducing overall assembly weight. The combination of an ultra-thin cross-section and low-friction metal shielding makes the 6810-ZZ the premier choice for applications demanding rapid rotational speeds, minimal heat generation, and strict space limitations.

Engineered for highly confined radial spaces, the 6810-2RS is an extra-light, single-row deep groove ball bearing belonging to the specialized 6800 thin-section series. It is equipped with dual-lip contact rubber seals bonded firmly to the outer raceway, creating a reliable barrier against fine particulate matter and fluid spray. Measuring a substantial 50 mm in inner diameter while maintaining a mere 65 mm outer diameter and 7 mm width, this component allows engineers to utilize wider, stiffer shafts without incurring penalties in machine bulk or weight. The combination of its thin cross-section and integrated sealing makes the 6810-2RS the primary choice for automated systems operating in environments compromised by dust, lint, or moisture.

The 6809-ZZ is a single-row, thin-section deep groove ball bearing from the 6800 series, fitted with non-contact pressed steel shields on both faces. Featuring a 45 mm bore and a highly compact 58 mm outer diameter, it occupies one of the slimmest profiles available for large-shaft metric ball bearings. This unique geometry—combining a large internal diameter with a minimal 7 mm cross-section—makes the 6809-ZZ the definitive choice for space-constrained assemblies where weight reduction and low-friction rotation are paramount. The double steel shields retain the factory grease fill while preventing the ingress of large particulate matter, ensuring extended service life without the thermal drag associated with rubber seals.

The 6809-2RS is a high-precision, single-row deep groove ball bearing belonging to the ultra-thin 6800 series. Equipped with dual-lip synthetic rubber contact seals on both sides, this bearing is engineered to deliver exceptional contamination exclusion and reliable grease retention within an extremely low-profile design. Featuring a 45 mm bore and a 58 mm outer diameter, it provides the ideal solution for large-shaft applications with severe radial space constraints. The factory-prefilled grease and robust rubber seals make the 6809-2RS the industry standard for compact, lightweight mechanisms operating in challenging environments containing dust, debris, or moisture.

The 6808-2RS is a single-row thin-section deep groove ball bearing from the 6800 series, fully sealed on both sides with contact rubber lips that ride directly against the inner ring shoulder. Featuring a 40 mm bore and a highly compact 52 mm outer diameter, it offers an exceptionally slim 7 mm cross-section. This geometry delivers essential weight reduction and space savings without sacrificing the contamination exclusion and long-term grease retention of a fully sealed unit. This combination—a large 40 mm bore within a narrow 52 mm envelope, integrated contact seals, and life-time lubrication—makes the 6808-2RS the optimal solution for precision machinery operating in dusty, damp, or debris-prone environments where standard-sized bearings would be too bulky or heavy.

The 6808 is a single-row, thin-section miniature deep groove ball bearing from the 6800 series, manufactured in an open configuration without shields or seals. Featuring a 40 mm bore and a highly compact 52 mm outer diameter, it delivers an extremely slim 7 mm cross-section. This open-type design is specifically engineered for internal machinery applications where the bearing operates within an already sealed housing, such as an oil bath or centralized lubrication system. By omitting the sealing components, the 6808 Open achieves the lowest possible starting and running torque, making it the premier choice for ultra-high-speed, space-constrained assemblies where frictional losses must be completely minimized.

Belonging to the ultra-compact 6800 series, the 6807-ZZ is a single-row, thin-section deep groove ball bearing equipped with dual metal shields. With a 35 mm bore, a 47 mm outer diameter, and a slim 7 mm profile, this bearing delivers exceptional space-saving advantages. Unlike open-type bearings, the 6807-ZZ features non-contact steel shields on both sides, making it a maintenance-free, factory-greased solution. It is specifically engineered to retain lubricants internally while effectively blocking dust, metallic shavings, and other external contaminants. This shielded configuration provides a perfect balance—offering robust environmental protection without introducing the heavy rotational drag associated with rubber seals, ensuring high-speed capability with minimal friction.

Engineered for uncompromising protection, the 6807-2RS is a single-row, thin-section deep groove ball bearing from the 6800 series, equipped with contact rubber seals on both sides. With a 35 mm inner bore and a 47 mm outer diameter, it maintains an ultra-slim 7 mm profile. Unlike open-type variants, this sealed design is purpose-built for external or exposed machinery where the bearing must defend against moisture, dust, and particulate contamination. Factory-packed with premium quality grease, the 6807-2RS locks in its own lubrication for the entirety of its lifespan. By utilizing heavy-duty NBR (Nitrile Butadiene Rubber) seals, this bearing minimizes maintenance requirements, making it the superior choice for space-constrained applications operating in demanding, less-than-clean environments.
