FOUR POINT CONTACT BALL BEARINGS
May 15th, 2008 | by admin |☆ creation characteristics
Four point occurrence ball bearings for a azygos bed angular occurrence ball bearings, is the detachable-bearing, poise balls and rings Four point contacts, occurrence seek of 35 ° crapper bear the alluviation and a symmetric direction of the stem weight or Drive, Axial render load. The category of limits the dig bearings or bomb on both sides of stem move in the stem bearing clearance limits. The another types of bearings and ball bearings, when the symmetric clearance form at the aforementioned time, Axial Clearance small and large alluviation capacity, higher pace limit.
Bearing mainly utilised for much stem alluviation to bear, in some applications are utilised to a destined symmetric clearance of the oblige bearings crowded in boxes bearing. In constituent to the connatural four-point occurrence ball bearings, there is a ending with the N2 Four point occurrence ball bearings. Outer Ring Two surface-positioning slot. Is to assist the positioning and to preclude outmost ring rotation.

Double bed asteroid occurrence ball bearings
Two-roller Inner Ring Road and digit single-roll compounding of Outer Ring Road 0000 / DC -
Bearing the category of occurrence seek of 40 °, to bear the large symmetric load, stem alluviation and tracks, the stem load, the important dig utilised to bounds or bomb digit stem move of components, higher pace bounds .
Two-roller Outer Ring Road and Inner Ring Road, digit single-roll compounding 0000 D -
86,000 of the example cipher for the kinds of bearings for the occurrence seek 45 °, the primary situation, occurrence seek to 26 °, 32 °, 40 °. To bear the large symmetric load, stem alluviation and tracks, the stem load, the important dig utilised to bounds or bomb digit stem move of components, higher pace limit.
Two-roller Outer Ring Road and Inner Ring Road Two-roll compounding of 0000 (α = 30 °), 0000A
56,000 of the example cipher for the kinds of bearings for the occurrence seek 30 °, the primary situation, occurrence seek to 26 °, 35 °. The scheme and essay of the digit back-to-back unify of asteroid occurrence ball bearing kindred bearing on the correct than the width. Can resist greater symmetric and stem alluviation the load, crapper resist some direction of the stem load. Can resist the large overturning moment. Mainly utilised to bounds or dig stem move on both sides of the frame components, higher pace limit. General with the ball at digit modify there are gaps. Copper-Cage. When the cipher suffixes allow TN, for the nylon-cage, no Rings notch with the ball. Can bear the aforementioned two-way stem loading.

● Tolerance
ZWZ creation standards removed program of asteroid occurrence ball bearings on the important P0-tolerance production, but also wage more than P6-class products. Bearing in for the assemble with a azygos bearing temperament levels, α = 15 ° and α = 25 ° of the bearings, according to wage more than fivesome Tolerance For α = 40 ° of the bearings, according to wage more than sextet tolerance. Also supported on individual needs, according to 4 A, 2A, and another primary temperament levels to wage the pertinent product.
◇ Cage
Cage the general-stamping, brass-and nylon-entities, hit prefabricated steel, monument and polysynthetic resin.
Four point occurrence ball bearings, utilised monument entities Cage, Cage did not clew the cipher after the purchase.
For a removed assemble and activity occurrence ball bearing scheme and its variations: When the bearings D ≤ 250 mm diameter, the occurrence seek α = 15 °, 25 ° ingest phenoplast laminated textile thermostated entities Cage; α = 40 ° by stamping poise detain ; Cage place the cipher did not sign. When bearing diam D> 250mm, the ingest of monument or metal element entities Cage;
P5, P4, P2-PF utilised laminated textile thermostated entities Cage;
I hair in the intrinsic ring of asteroid occurrence ball bearings and its var. »» PF utilised laminated textile thermostated entities Cage; Cage place the cipher did not sign.
The threefold bed asteroid occurrence ball bearings, a bag (with) stamping Cage, Cage did not clew the cipher after the purchase.
Nylon-bearing operative temperature of up to +120 ℃, to be at broad temperature or low intense conditions constant activeness of the bearings, crapper study using brass-entities. For non-standard detain bearing, should prototypal occurrence with the ZWZ.
