Small Deep Groove Ball Bearing | Small Size Ball Bearings Under 30mm Bore

Small deep groove ball bearing is one of the most versatile rolling bearing solutions widely adopted in compact mechanical assemblies across many industries. As a trusted bearing supplier, we provide a full range of small deep groove ball bearing options engineered for equipment designs where space is limited and reliable continuous rotation is essential. These compact bearings are designed to support both radial loads and moderate axial loads, making them the preferred choice for countless small motor and portable device applications.

When engineers search for a small deep groove ball bearing, the most common requirement is a bore diameter within 30mm. This size range covers the 60, 62, 63, 68 and 69 bearing series, all of which sit within our regular stock inventory. Buyers can select shielded ZZ variants or sealed 2RS versions. ZZ metal shields block coarse dust particles, while 2RS rubber seals deliver stronger protection against fine dust and light moisture, extending service life in harsher operating environments.

Material selection is a key consideration when picking a small deep groove ball bearing. Carbon steel options offer cost-effective performance for general indoor applications such as home appliance motors and handheld equipment. Stainless steel small deep groove ball bearing models are recommended for humid environments or equipment exposed to mild chemical corrosion, including some portable medical instruments and outdoor power tools.

Many people confuse small deep groove ball bearing with miniature deep groove ball bearings. While both belong to compact ball bearing categories, miniature deep groove ball bearings cover even smaller bore sizes for ultra-precision assemblies. Small deep groove ball bearing balances compact dimension and higher load capacity, which makes it suitable for bearings for handheld power tools, home appliance motors, small fan assemblies and fishing reel gear systems.

Bearings for handheld power tools are a major application field for small deep groove ball bearing. Power tools such as electric drills, angle grinders and trimmers generate high rotation speed and vibration during operation. A properly selected small deep groove ball bearing can withstand temperature rise and intermittent shock load, reducing noise and preventing premature failure. Many tool designers choose these bearings for prototype testing before mass production.

Home appliance designers also rely heavily on small deep groove ball bearing. Inside blenders, cooling fans, oven motors and small vacuum machines, low-noise operation is a core product selling point. A reliable home appliances bearing supplier understands that appliance motors require bearings that can endure frequent start-stop cycles and maintain quiet performance over years of household use. Our small deep groove ball bearing line is frequently sampled by home appliance developers for product validation.

Wuxi Jakstar Precision Bearing Co., Ltd, based in Wuxi China, specializes in precision compact bearings and exports products to customers worldwide. Our markets cover Turkey, Italy, South Korea and many other regions. We have welcomed Turkish customers to our premises for on-site visits and technical discussions. These face-to-face meetings help us fully understand local application demands and deliver bearing solutions that match regional industrial standards. Our global customer base continues to expand, as engineers across different countries value our stable quality and flexible sample service.

When you source small deep groove ball bearing from our team, we support flexible order arrangements. We provide small quantity samples for lab testing, prototype evaluation and new product development. If your project requires non-standard internal clearance, special lubrication or customized dimensions, our technical team can review your specification sheet and match suitable bearing solutions. We do not enforce large minimum order quantities, which is ideal for equipment designers and small batch manufacturers.

How to select the correct small deep groove ball bearing for your project? You need to confirm four core parameters: bore size, outer diameter, working speed and load type. Operating temperature and environmental dust level also influence seal and material choices. If you are unsure about bearing selection, share your equipment design requirements with our technical team, and we can help narrow down suitable bearing types.
