    Looking to replace my bearings on my Masterflex pump head. Have no idea what to get, and have this shop near me: https://www.applied.com/categories/bearings/ball-bearings/c/84

    Anyone know which I should get, or just any whatever is the exact same size as the old ones? Price ranges from cheap to uber expensive. Thanks.

    He did list bearing information, but for the motor, and not the head. I guess it should be similar though. The pump heads probably vary in bearing type and size between models too I assume.

    Motor bearings from rc thread.
    - Front Bearing, 608 Double Sealed
    - Rear Bearing, R6 Double Sealed

    Actually looked on my bearing, and it shows "R8L8". So I guess it is R8 size, but no idea what L8 is. I'll assume it should be double sealed, so R8-2RS is what I should find. I think the previous owner had some tubing splits, never washed off the salt water, and rusted the bearings.
