Mardatt 16mm Precision Bearing Steel Balls, 15-Piece Set

For servicing a bicycle bearing or replacing a worn ball in suitable mechanical equipment, this Mardatt set provides 15 precision bearing steel balls, each measuring 16mm. The shared size makes it straightforward to select a ball for a repair that calls for this specific diameter.

A bearing repair often calls for a small number of matching replacement balls, while general workshop storage benefits from keeping spares organized. This set addresses both needs with a compact plastic case and balls kept in separate packaging.

Use them in compatible applications such as bicycles, motorcycles, casters, drawer slides or household furniture. Their bearing-steel construction and smooth finish suit jobs where consistent rolling contact matters.

What stands out

Each ball is made from high-hardness bearing steel and heat-treated for strength and resistance to deformation over time. The precision finish is smooth, with no residual burrs described, supporting use in a bearing where the balls move between the inner and outer rings. In that role, the balls help reduce friction as the bearing rotates, which can limit wear on the equipment.

The balls arrive with a small amount of grease, supporting lubrication and helping protect against rust and corrosion. The plastic storage case keeps the set together for workshop use or transport. Separate packaging and a size label help keep the balls organized and make it easier to identify the size when selecting a replacement.

Quick overview

• Type: Bearing steel balls
• Size: 16mm diameter
• Quantity: 15
• Material: Bearing steel
• Compatible lubricant: Grease
• Storage: Plastic case

The stated applications include bicycles, motorcycles, casters, auto parts, valves, refrigerators, air conditioners, photographic equipment, drawer slides and household furniture. That range makes the set useful for repair tasks across different types of equipment, rather than only bicycle maintenance. Choose it for a bearing or mechanism designed for 16mm balls, the diameter is the key fit detail when selecting replacements.

How to use it

For a practical repair, first identify the bearing or mechanism that needs a replacement and confirm that it uses 16mm balls. Place the balls in the bearing’s intended rolling path between its inner and outer rings, following the equipment’s normal assembly arrangement. The supplied grease supports lubrication during use, and the case gives you a place to keep any remaining balls together after the repair.

For a bicycle or caster service, for example, the set gives you matching-size balls for a component that calls for 16mm replacements. For a furniture slide or another listed application, the same approach applies: match the ball diameter to the mechanism’s requirements, then use the balls in the appropriate bearing assembly. This is a focused replacement set, not a mixed-size assortment, so it suits repairs where the required size is already known.

Should you buy it?

Worth considering if your repair calls for 16mm bearing balls and you want several matching spares stored together. The set combines bearing steel, a smooth precision finish, heat treatment and a light grease coating in a portable plastic case. It is suited to maintenance across compatible bicycle, motorcycle, caster and household mechanisms, giving repairers a clearly sized supply for work where correctly matched rolling components help reduce friction.
