Description

5/8" x 1-3/8" Steel Ball Bearings for Racing Kart & Lawnmower Front Hubs


Our 5/8" x 1-3/8" standard steel ball bearings are designed for high-performance front hubs on modern LTO (Left Turn Only) racing go-karts and racing lawnmowers. Built with low-contact seals and minimal factory grease (unless otherwise noted), these bearings are optimized for low rolling resistance and free-spinning performance on the track.


They serve as direct replacements for the popular 2531 5/8" front hub and are compatible with most standard 5/8" kart hubs.

For best performance and longevity, we recommend oiling your bearings before every race day using a quality bearing lubricant such as Lubtek or TRI-FLO. Avoid using penetrating oils for lubrication(only use for cleaning bearings), which are not formulated for bearing life.


Bearing Specifications:

  • Inside Diameter (ID): 0.625" (5/8")
  • Outside Diameter (OD): 1.375" (1-3/8")
  • Width: 0.430"
  • Design: Steel ball bearing with low-contact seals
  • Lubrication: Light or no grease (oil recommended)


Key Features:

  • Ideal for LTO racing go-karts and racing mowers
  • Free-spinning design for maximum speed and efficiency
  • Compatible with 2531 hubs and most 5/8" kart front hubs
  • Durable steel construction for racing environments
  • Easy to maintain—oil regularly for top performance


Maximize your kart’s speed and steering response with precision bearings trusted by competitive racers.

FAQ

Q1: What size are these bearings?

A: These bearings have a 5/8" inside diameter (0.625"), 1-3/8" outside diameter (1.375"), and a width of 0.430".


Q2: What hubs are these compatible with?

A: They are direct replacements for 2531 5/8" front hubs and fit most standard 5/8" go-kart and racing mower front hubs.


Q3: Are these bearings pre-lubricated?

A: These bearings have low-contact seals and are lightly greased (or dry, depending on batch) to allow free spinning. We recommend oiling them before each race.


Q4: What type of oil should I use on these bearings?

A: Use a light bearing oil such as Lubtek or TRI-FLO. Do not use penetrating oils, as they are not suitable for bearing lubrication.


Q5: Why choose low-contact seal bearings for racing?

A: Low-contact seals reduce friction and rolling resistance, allowing for faster wheel spin and better performance during competition.
