6802 Deep Groove Ball Bearing 15x24x5mm

When a 15mm shaft must fit within a 24mm OD housing, the 6802 bearing is the thinnest option in its bore class. At 15x24x5mm, it saves 4mm OD and 2mm width versus a 6902 bearing (15x28x7mm), trading load capacity for space. This page covers the 6802 bearing specifications, sealing options, performance limits, and the design decisions that justify choosing it over the wider 15mm-bore alternatives.

6802 Bearing

Model	6802
Bore (d)	15 mm
OD (D)	24 mm
Width (B)	5 mm
Type	Open / Shielded / Sealed
ABEC	ABEC-1 / ABEC-3
Dynamic Load	2.08 kN
Static Load	1.26 kN
Max Speed	32,000 RPM (open/ZZ)

The 6802 bearing is a thin-section deep groove ball bearing with 15mm bore, 24mm OD, and 5mm width. Available in open, ZZ (metal shields), and 2RS (rubber seals) configurations. At 2.08 kN dynamic load and 32,000 RPM in open/ZZ configuration, it suits compact mechanical designs where radial space and weight are constrained. The 2RS sealed variant derates to approximately 1.40 kN and 24,000 RPM for contaminated environments.

Shielding and Lubrication

Three sealing configurations serve different environments. Open 6802 bearings run at 32,000 RPM with no seal friction, requiring external lubrication and a clean housing. ZZ bearings use non-contact SPCC steel shields pressed into the outer ring on both sides; they retain factory grease without adding drag, preserving the full speed rating. 2RS bearings use nitrile rubber (NBR) lip seals that press against the inner ring, blocking moisture and fine dust at the cost of friction, lowering the speed ceiling to approximately 24,000 RPM.

At 5mm width, the 6802 bearing carries a smaller grease reservoir than wider bearings in the 15mm-bore class. The 2RS configuration retains lubricant longer when relubrication access is limited. ZZ or open configurations suit designs where maximum speed takes priority over contamination exclusion.

Performance

Within the 15mm-bore bearing family, the 6802 bearing is the thinnest-section option. The 6902 bearing (15x28x7mm) reaches 4.30 kN dynamic load, more than double the 6802 bearing rating, at the cost of 4mm additional OD and 2mm width. The 6002 bearing (15x32x9mm) delivers 5.60 kN but requires nearly double the OD cross-section. The 6802 bearing trades load capacity for extreme compactness: 2.08 kN dynamic and 1.26 kN static in open or ZZ configurations. For 2RS sealed variants, dynamic load derates to approximately 1.40 kN with speed capped at 24,000 RPM.

OEM and Customization

Yuanhe manufactures 6802 bearings to customer specifications. Custom internal clearance grades C2, CN, and C3 are available for volume orders. Low-noise grease fills (V2 or V3 vibration class) support quiet-operation requirements in medical devices and office equipment. 440C stainless steel rings and balls provide corrosion resistance for food processing and laboratory environments. Standard OEM lead time is 7 to 15 days. Send bearing dimensions or part number requirements to contact Yuanhe for a quote.

Frequently Asked Questions

What does ZZ mean on a 6802 bearing? +

ZZ indicates double metal shields (SPCC steel) pressed into the outer ring on both sides. These non-contact shields retain factory grease and block larger particles while adding zero friction. The 6802 ZZ bearing reaches the full 32,000 RPM speed rating, making it the right choice for clean, high-speed applications where contamination is not a primary concern.

When should I choose a 6802 bearing over a 6902 bearing? +

Specify the 6802 bearing when the housing radial space is capped at 24mm OD or the width budget is under 6mm. The 6902 bearing requires 28mm OD and 7mm width. The 6802 bearing saves 4mm in diameter and 2mm in width, fitting into drone arms, compact motor housings, and tight automation assemblies. If space permits 28mm OD, the 6902 bearing delivers more than double the dynamic load capacity (4.30 kN vs 2.08 kN).

Does the 6802 bearing need a minimum load for quiet operation? +

Yes. Thin-section bearings like the 6802 require a minimum radial load of roughly 2 to 3 percent of the dynamic rating to prevent ball skidding. Below approximately 0.04 kN, the balls may slide instead of roll, generating noise and surface wear. Light-load applications such as small instrument fans and positioning stages should apply a spring preload or specify low-noise grease to maintain quiet operation.

Can I order 6802 bearings in stainless steel? +

Yes. Yuanhe offers 6802 bearings with AISI 440C stainless steel rings and balls for corrosion resistance in food processing, laboratory instruments, and marine applications. Stainless 6802 bearings carry approximately 80 percent of the chrome steel load ratings. Standard OEM lead time is 10 to 15 days for stainless configurations.
