Donepart 5/8″ ID x 1-3/8″ OD Double Sealed Bearings (4 Pack)
These 99502H-2RS bearings measure 5/8″ bore (ID) and 1-3/8″ outer diameter (OD) with a 0.433″ thickness. They feature double rubber seals (2RS) and arrive pre-lubricated. The set includes four bearings compatible with go kart axles and lawn mower spindles. They are direct replacements for major brands such as MTD, Prime Line, Ariens, and Troy-Bilt. Best for: owners replacing standard-size go kart axles or mower deck spindles with a common 5/8″ bore. Limitation: confirm your old part number to ensure exact fit, as minor model variations can exist.
AR-PRO 4-Pack 5/8″ Bearings (Carbon Steel)
These universal 5/8″ bore bearings offer a robust carbon steel construction, designed for long-lasting wear. They are suitable for replacing 5/8″ wheel bearings on wheelbarrows, carts, hand trucks, and lawnmowers, making them a flexible option for go-kart projects that reuse common axle sizes. Best for: buyers seeking a versatile bearing that can serve multiple equipment types. Limitation: they are described as universal rather than kart-specific, so verify axle dimensions before ordering.
LIZEWEI Go-Kart Axle Bearing Kit (1 Inch)
This kit centers on a 1″ live axle with three-hole flangette mounting options. It includes bearings, hangers, flangettes, bolts, and locknuts for a complete install. Best for: kart owners needing a full mounting solution with robust 3-hole flange compatibility. Limitation: ensure your axle and flange configuration match the kit’s three-hole pattern before purchase.
GUCIDDAK 1″ Live Axle Bearing Kit with 3-Hole Flangettes
This kit provides a complete 1″ live axle bearing solution with three-hole flangettes for mounting. It emphasizes solid steel construction and stabilization to reduce wheel shake and noise during turns. Best for: go-karts or mini bikes needing a heavier-duty, reliable axle bearing package. Limitation: kit contents and fit depend on the specific three-hole flange pattern; verify compatibility with your frame.
ZOZYOYE 1″ Live Axle Bearing Kit
Designed for go-karts and mini bikes, this 1″ live axle bearing kit includes three-hole flanged hangers for stable mounting. Best for: riders who want straightforward installation and reliable highway-ready performance. Limitation: product descriptions emphasize general compatibility; check your specific axle diameter and mounting hole pattern to avoid mismatch.
DEEG 10PCS 99502HNR Wheel Bearings
This set provides 5/8″ ID x 1-3/8″ OD bearings with chrome steel construction, double-sided rubber seals, and a high-speed rating up to 20,000 rpm. They are designed for low noise and robust grease retention. Best for: go-kart projects requiring a high-speed, sealed bearing option. Limitation: ensure the 5/8″ bore matches your axle; some models may require different thickness or seal type.
Tonmp SBPFL205-16 Pillow Block Bearings (2-Pack)
These flange-mounted bearing units come with a stamped housing and a complete pre-assembled bearing. They fit a 1″ bore and include two mounting holes for secure installation. Best for: setups needing easy drop-in replacement with added flange support. Limitation: flange housing materials are stamped steel; consider environment exposure and mounting torque requirements.
Buying Guide: Key Purchase Considerations
- Axle diameter and bore match: Verify the bore size (ID) and outer diameter (OD) to ensure a proper fit on your go kart axle.
- Seals and lubrication: Sealed (2RS) bearings retain grease and resist dirt; unsealed bearings require lubrication and may wear faster in dusty environments.
- Flange and mounting: If your kart uses three-hole flangettes or pillow block housings, confirm hole patterns and bolt sizes before buying.
- Material and finish: Carbon steel cores are common; chrome steel offers enhanced hardness. Consider corrosion resistance for outdoor use.
- Speed and load ratings: For high-speed go kart use, ensure bearings can handle rpm and load without excessive heat or noise.
- Replacement compatibility: Some parts claim direct replacement for specific brands. Cross-check part numbers and old components to avoid mismatches.
Frequently Asked Questions
- What bearing size is most common for go karts? Many karts use 5/8″ bore bearings or 1″ bore bearings, depending on axle diameter. Always measure your axle before purchasing.
- Should I choose sealed or unsealed bearings for outdoor use? Sealed bearings (2RS) are generally better for outdoor use because they resist moisture and debris, reducing maintenance.
- Are bearing kits with flangettes easier to install? Yes. Flanged or pillow block designs provide stable mounting and may simplify alignment on a DIY kart frame.
- Can I use wheel bearings from other equipment for a go kart? In many cases, yes, if the bore, OD, and mounting pattern match. Always verify compatibility with your axle and hub.
- Do all kits include installation hardware? Some kits include hangers, flangettes, bolts, and locknuts. Check the product list to confirm included components.
- What maintenance is recommended for go kart bearings? Regularly inspect seals, clean debris, relubricate if applicable, and replace bearings showing excessive play or noise.
