What does 608 mean for bearings?
What does 608 mean for bearings?
The standard inline skates bearings have the designation “608”. The “608” means that the bearings are from the 600 series, with a 8mm inner diameter (the width of the hole, i.e., internal bore).
What temperature should I heat my bearings?
Hot mounting Normally a bearing temperature of 80 to 90 °C (144 to 162 °F) above that of the shaft is sufficient for mounting. Never heat a bearing to a temperature greater than 125 °C (257 °F), because the material may change metallurgically and produce alterations in diameter or hardness.
What is the difference between 608z and 608zz bearings?
608z is single shielded and 608zz is double shielded. Same bearing other than that.
What is the best ABEC rating?
ABEC 1 is the most crude, the least precise, the most durable, and the cheapest. ABEC 3 is what most cheap complete skateboards come with, especially skateboards from China. ABEC 3 bearings work for most skateboarding, but won’t roll very smoothly or fast. ABEC 5 bearings are the norm in skateboarding.
Do bearings expand when heated?
In addition, the temperature must be high enough (maximum of 130°C for a bearing) to generate sufficient expansion and temporarily loosen the fit, so that the sprocket or bearing can easily be mounted. The heating temperature depends on the ambient temperature and also the fit and material of the bearing seat.
Can you heat up sealed bearings?
■ Bearings should never be heated over 120°C. This temperature mounting method cannot be used for pre-greased and sealed bearings or shielded bearings.
What does 608RS bearing mean?
Rubber shield
EG 608RS or 6082RS. “RS” simply stands for “Rubber shield.” It specifically denotes a “Non Contact” rubber shield, which only contact the outer race – not the inner. Sometimes you will see “2RS” on a bearing code – this simply means that both sides of the bearing have rubber shields.
What size is a 608ZZ bearing?

How do I Choose an induction heater for bearing heating applications?
The comprehensive range of SKF induction heaters is suitable for most bearing heating applications. The selection chart below gives general information on choosing an induction heater for bearing heating applications. For heating components other than bearings, SKF recommends the use of a TIH L MB series heater.
What does the SKF M20 value mean?
The SKF m20 value indicates the weight (kg) of the heaviest SKF spherical roller bearing of series 231 that can be heated from 20 to 110 °C (68 to 230 °F) in 20 minutes. This defines the heater’s power output instead of its power consumption.
What is the best way to heat bearings?
Induction heaters (D) are the modern, efficient and safe way to heat bearings. In operation, they are generally faster, cleaner, more controllable, and easier to use than other heating methods. The comprehensive SKF induction heater range can be used for efficiently heating bearings and work pieces, both large and small.
