Miniature ball bearings come in different types and various designs to meet virtually any precision instrument application requirement. Some of the bearing types include high-speed radial, full ball complement, radial retainer, angular contact, thrust, and pivot.

Many cars have clutches that work hydraulically. The mechanism that operates them is sturdy and long lasting, requiring only an occasional look in the fluid reservoir (See Checking and removing a clutch master cylinder ) to make sure the level is correct.

Visit our Online Catalog Our miniature ball bearings have excellent frictional torque performance, making them a perfect fit for a range of high-speed motor applications. You can get our instrument ball bearings in steel, chrome, or stainless steel.

Instrument ball bearings are used in a variety of applications, including dent handpieces, motors, medical devices, the crusher industry, automotive, mining sector, agriculture, the textile industry, metal industry, home appliances, fluid machinery, and heavy machinery. We also have extra-miniature bearings, extra-thin-type bearings, flanged bearings, extra-thin-type flanged bearings, and large-sized stainless steel bearings.

Clutch fluid is the same as that used in braking systems, and must conform to strict international specifications. It should come in a sealed, airtight container bearing one of the three current specification marks: SAE J1703, US FMVSS or 116 DOT 3.

Leakages let air into the system, causing erratic pedal response. After the trouble has been located and put right, bleed the clutch to expel air and replace it with clean, uncontaminated fluid.

Top up to the correct level with new clutch fluid. After pouring liquid , tightly replace the container lid, or moisture will get into the liquid and spoil it.

Miniature ball bearings, also referred to as precision ball bearings or instrument ball bearings, are micro bearings used for extremely high speeds. Instrument ball bearings have bore diameters that do not exceed 0.3937”. The size of these bearings allow them to rotate at high speeds with minimal vibration or noise.

Get a helper to press the clutch pedal smartly all the way down, then release it quickly. If bubbles flow from the end of the pipe in the jar, pump the pedal until no more appear. Keep the end of the tube immersed in the fluid all the time.

SPB-USA LLC offers a huge selection of miniature bearings in both inch and metric designations for maximum compatibility across various applications. We offer bearings in dimensions as small as 0.6mm bore diameters and are a recognized leader in the manufacture of precision ball bearings and other medium-sized bearings.

Hydraulic fluid is highly poisonous and corrosive. If you get some in your eye, flush it with clean water for 15 minutes, and call a doctor.

Extra small and miniature bearings are usually sealed with rubber seals and shields to prevent any possible lubricant leakages or dust entry. This facilitates easy handling, while sealing devices also enable a seamless process.

Top up the fluid reservoir and screw the cap on firmly. Get your helper to work the pedal vigorously several times while you inspect all the joints and piping of the system for leaks.

If after six pedal strokes the bubbles have not cleared, top up the reservoir before you continue pumping. Otherwise, more air will be drawn into the system and it will have to be bled again.

Miniature ball bearings are used in a variety of applications because they help reduce friction between parts that move independently — while also saving on space in tight areas such as in semiconductor equipment, medical applications, and instrumentation.

No matter what kind of project you have, there are a range of ball-bearing sizes to suit your application. These small bearings are usually machined, and they include the inner ring, outer ring, snap rings, retainers, shields, and balls.

If the pedal still does not work the clutch effectively, examine the places where the pushrods enter the master cylinder and slave cylinder , peeling back the rubber dust covers. The fluid is probably leaking past the seals (See Checking and removing a clutch master cylinder ).

SPB-USA LLC has consistently offered high-quality EZO Precision Ball Bearings across various industrial, scientific, and commercial applications. Available in both metric and inch designations, our miniature ball bearings are recognized for their high-level performance capabilities that accommodate rotation with extremely low friction.

Remove the cover and clean the nipple thoroughly. Fit the end of the bleed tube securely over the nipple. It must be a tight, push-on fit.

Remove the bleed-nipple dust cover on the slave cylinder and fit the bleed tube as described (see right). The nipple is easily damaged, so use a spanner of the right size to unscrew it about three-quarters of a turn.

If the fluid level in the reservoir is more than 6mm below the top (or the full mark), inspect the whole system immediately for leaks.

We have perfected the art of manufacturing miniature ball bearings, so we always maintain the highest quality standards. Therefore, our EZO bearings have the exact characteristics you need for a lasting performance. Reach out to our team today for more details about EZO Precision Ball Bearings or request a quote.

Put the free end of the bleed tube into the jar, below the surface of the fluid. Air and fluid from the system will be pumped into the jar.

Most cars use a type of fluid containing polyalkylene glycol ethers, but some use a mineral-based fluid. Check your car handbook - on no account should the two types be mixed.
