## Overview

## Description

This 608ZZ 8x22x7 shielded greased miniature ball bearing by BC Precision is a single-row bearing for supporting radial loads. The bearing is made of chrome steel for durability and resistant to deformity under heavy loads, and is double-shielded to keep lubricant in and contaminants out. it has a revolutions per minute (RPM) limit of 34,000 with grease lubrication. The dimensions of this bearing make it suitable for use in skateboards, inline skates, and scooters, among others. Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

Review: Fit our Bissel upright vacuum brush roller and got it going again. - These were purchased for a Bissel upright vacuum cleaner. My mom's vacuum broke a belt, so I put another one on. The vacuum didn't pick stuff up like it should, so I looked at it again and the new belt was also broken. Upon disassembly one of the rotating brush roller bearings had seized up so the drive shaft was spinning but the belt wasn't moving, so it heated up and broke. I tried to source new bearings locally but came up with nothing. The bearing size was on the old bearing and luckily I found these on desertcart. Both roller bearings on the brush roller were replaced and the vacuum went back to working like new again. No tools other than a hammer and screwdriver were required. Saved $100 fixing the vacuum.
Review: High Quality Bearings - I replaced the bearings in an old Pearl P-120P bass drum pedal with these. They have smooth action, they're quiet and have high build quality! Will definitely buy these again!

## Questions & Answers

**Q: Mine are 608zz SG9 are these SG9? better? Worse?**
A: Same so far.. used in roller on vacuum.. been in for a year..

**Q: What is the id and od in inches?**
A: ID is 0.312 inches or 5/16 inches or 7.71mm
OD is 0.8665 inches or 111/128 inches or 22.01mm

**Q: Can you disassemble these and put the balls, ball frame and guards on another just like it? I need it for a motorized bicycle chain tensionser wheel.**
A: I don't know about disassembling without likely severe damage.  However, I used parts from an old bicycle derailleur to tense and carry the double length chain for my old Infinity Recumbent Bike.  The springs give just enough to allow the chain to move all directions without choking.  Stiff strapping was easy to use to mount on frame.  Later I used small radiator hose clamps to secure the whole contraption for rough rides.  It's held together and still works after 10 years and about 8,000 miles.  If you find a toothed wheel that fits your bearings, you could let it ride on a strait shaft and avoid my Rub Goldberg styling.

**Q: Where are these made?**
A: There is nothing on the bearing that indicates to me where it was made.  The only thing on them other than the 608zz is CQC. I assume that is the company that made them. Without trying to track down a company with CQC initials, based on price, etc. I’d say the odds are they were made in China.  Regardless they seem to be of good quality and work just fine in the guides on my band saw.
