A quality inline micro bearing. ABEC 11 bearings are used by the serious
inline skater who wants the best. The manufacturing of this bearing is difficult
and costly. The tolerances are very tight and they have virtually no friction
under the load of your weight. They are truly a nice bearing to experience for
any kind of inline skater. Bearings are gel
lubricated and sealed for long lasting low maintenance.
Black Panther ABEC 11's are smooth. A step above both the ABEC 3 and 5.
These bearings consist of long lasting polished ball bearings and races,
lubricated with genuine Teflon oil, speed washers, and Derlin core for strength
and resistance. Removable rubber coated shield makes for easy cleaning and water
resistance. Set of 8 includes free bearing spacers.
The SRG [abec 11 bearings] are solid, and they do what bearings are
supposed to do--spin and last. Over the past 6 years, we've been selling
complete longboards in our online shop, and we've sourced a lot of stock
bearings during that period. Some were good, some decent, and some not so good.
These are the best Abec 11 bearings we've found. They're good, they're cheap,
and they last. We believe in them enough to put our name on them. Pop them in
and don't worry about getting them dirty.
SRG Bearings are the first precision bearing designed for skateboarding
that incorporates an integrated spacer and washer. The perfectly faced inner
races provides precise spacing and perfect alignment so that the locknuts can be
snuggly tightened without pinching or binding the bearings. The bearings work
together to more evenly share the sideloads and keep your wheels flat on the
ground for better wear. This patented system is guaranteed to give you the
fastest and strongest bearings on the planet. They fit all skateboard wheels
that use the industry standard .400" spacing (10.16mm). Tested by the world's
fastest skateboarders in the most demanding conditions, Biltins provide
unparalleled performance in all types of skating. They are also the easiest skf bearings to use, making those nasty little
washers and annoying spacers a thing of the past. Designed to be easier to
maintain than other bearings, Biltins are simply the best and fastest skateboard
bearings on the market today.
Tolerance classes for ball bearings were defined by a committee within the
ABMA known as the “Annular Bearings Engineers Committee” (ABEC). These
tolerances are commonly referred to as ABEC rating, or grade. Tolerance classes
for roller bearings are covered by the RBEC classifications contained within the
same standard. These classes are defined in ABMA standard 20 – Radial Bearings
of Ball, Cylindrical Roller, and Spherical Roller Types and ABMA standards 12.1
and 12.2 – Instrument Ball Bearings. The ABEC (and RBEC) tolerance
classifications specify both tolerances of size and form for the individual
inner and outer rings. The critical features of the rings include the bore (or
inner diameter of the inner ring), the outer diameter of the outer ring, the
ring widths, and the raceways of each ring. Tolerances of form include
roundness, taper, runout, and parallelism.
ABMA standard 20 defines 5 classes: ABEC 1, ABEC 3, ABEC 5, ABEC 11, and
ABEC 9. Instrument series ball bearings are defined in standards 12.1 and 12.2
and carry the suffix “P”. Extra thin and thin section ball bearings defined in
standards 12.1 and 12.2 carry the suffix “T”. The higher the number of the
classification, the tighter the tolerances become resulting in higher precision
of the assembled iko bearing. When the
classification system was first set up, machine tool technology was such that
manufacturers mass produced only ABEC 1, and sometimes ABEC 3. Bearings for the
higher classifications were selected from the production runs of the lower
classification. Today, the technology has advanced to the point where
manufacturers can produce ABEC 11 and ABEC 9 bearings routinely.
