6003-2RS Bearing 17x35x10mm - Lubricated Sealed Ball Bearings

In this review the focus is on a sealed radial ball bearing set designed for routine and demanding shop use: the 6003-2RS 17x35x10mm pack. The bottom line is straightforward - these bearings suit users who need a durable, low-maintenance bearing that tolerates high rpm and impacts. For mechanics replacing worn hub or pulley bearings or hobbyists upgrading kart hubs, the main reason to buy is the combination of chrome steel construction and a dual-sided rubber seal that reduces contamination and replacement frequency.

Key Features

• Chrome steel race: Provides high impact resistance and helps reduce metal fatigue under repeated loads.
• Dual-sided rubber seal: Keeps dirt and grease in place so bearings run cleaner and require less frequent replacement.
• Lubricated for high rpm: Pre-lubrication supports extreme rotational speeds and minimizes early wear.
• Versatile 17x35x10mm size: Fits common light industrial applications such as small motors, kart hubs, and pulleys.
• Locally designed in USA: Product design and quality oversight are performed in South Florida to meet regional service expectations.

Who It's For

These bearings are best for technicians, small workshop owners, and hobbyists who need reliable sealed bearings for light to moderate-duty machinery. They are particularly useful where contamination is likely and where replacing bearings often is costly or impractical.

Those who need highest-precision, ultra-low-friction bearings for timed racing applications or bearings with exotic corrosion-resistant alloys should look elsewhere; while durable and high rpm rated, these are chrome steel sealed bearings intended for general industrial and consumer use.

Pros & Cons

Pros

• Durable chrome steel construction reduces the chance of metal fatigue under impact.
• Dual rubber seals protect the interior and extend time between service intervals.
• Pre-lubricated design supports higher rpm and helps prevent early wear.

Cons

• Some users report a mixed fit and occasional sluggish spin rate compared with higher-precision bearings.

Frequently Asked Questions

Are these bearings pre-lubricated?
Yes, they come lubricated to support higher rpm and reduce initial break-in time.

Can these be used on kart hubs?
Yes, customers have used them successfully on kart hubs, though fit and spin characteristics can vary by hub tolerance.

Are they corrosion resistant?
They are chrome steel and resist impact and fatigue, but they are not stainless; avoid prolonged exposure to corrosive environments.
