GEARWRENCH Hand Bearing Packer 2775D — Portable 2in Bore, Transparent Cup, Self-Contained

The GEARWRENCH Hand Bearing Packer 2775D is a self-contained, portable tool that quickly and cleanly fills cage-type roller and ball bearings up to a 2" bore without a grease gun or air line.

The 2775D bearing packer combines a clear, impact-resistant cup and a compact pump mechanism so technicians, hobbyists, and mobile mechanics can pack bearings on the job. Built to GEARWRENCH standards, it replaces fumbling with loose grease and reduces mess while letting you watch grease levels through the transparent cup. It’s designed for repeated use and engineered to deliver consistent fills for up to 50–60 bearings per fill.

How does the 2775D speed up bearing service?

The integrated pump and self-contained cup eliminate trips to a bench grease gun, letting you work wherever the vehicle or machine is located. Quick setup and a steady, controllable flow reduce time spent maneuvering small bearings and cleanup afterward.

• Packs 50–60 bearings per full cup to reduce refills
• No air line or external grease gun required for onsite work
• Transparent cup lets you see when to refill, avoiding interruptions

Which bearings and sizes can this packer handle?

The 2775D is built for cage-type roller and ball bearings with bores up to 2 inches (50.8 mm). It accommodates common automotive and light-industrial bearing sizes used in wheel hubs, transmissions, and small machinery.

• Compatible with cage-type roller and ball bearings
• Maximum bore capacity: 2" (50.8 mm)
• Suitable for typical automotive and light-industrial bearing dimensions

What features make the cup and pump durable and easy to use?

The cup is crafted from impact-resistant transparent material so you can monitor grease quantity and quality. The hand-operated mechanism is compact and built for repetitive cycles, giving reliable, consistent packing without specialized equipment.

• Transparent, impact-resistant cup for visual grease checks
• Self-contained design prevents grease contamination and mess
• Compact pump engineered for everyday, repeated use

How do I get the cleanest, most consistent pack every time?

Use clean bearing-grade grease and fill the cup to the recommended level before starting. Seat the bearing on the adapter or bore, operate the pump evenly, and rotate the bearing if needed to work grease into all rollers or balls.

• Fill with fresh bearing grease to avoid contamination
• Place bearing squarely on the bore adapter for uniform flow
• Operate pump steadily and rotate bearing for complete coverage

Who is this for: The GEARWRENCH 2775D Hand Bearing Packer is aimed at professional technicians, mobile mechanics, maintenance crews, and DIYers who need a portable, efficient way to pack bearings without a bench-mounted pump or shop compressor. If you service wheel bearings, small industrial rollers, or field equipment and want a cleaner, faster method with visible grease monitoring, this tool is a practical addition to your kit.
