Material and bearing form are separate choices
The catalogue separates ceramic, plastic, stainless-steel and non-standard families. Its named references include 1204CE self-aligning bearings, UC205CE ceramic inserts, POMUC205 plastic inserts, 6800PEEK and S51100 stainless thrust bearings. [3] These names are not one material-independent load or life rating.
Ceramic self-aligning bearing
The detailed 1204CE page offers zirconia, silicon-nitride and silicon-carbide material options without assigning one exact construction to every part. Confirm rings, balls, cage and any seals individually.
1204CE component review →Insert bearing or plastic variant
UC205CE and POMUC205 refer to different entries from 1204CE. Check housing/locking arrangements and material-specific duty; their geometry and claims cannot fill a self-aligning bearing’s specification.
Stainless or non-standard bearing
Request the actual steel/material grade or custom drawing, selected construction and operating limits. A general corrosion-resistant label does not settle the full assembly.
UC205CE is an insert-bearing reference; 1204CE is a self-aligning bearing reference. Select the bearing form first, then confirm the proposed ceramic construction. Material wording attached to one entry cannot specify every ceramic family.
What the company evidence supports
The introduction identifies 军旺(嘉兴)轴承制造有限公司 and describes ceramic/plastic bearing manufacture and research. It mentions Shanghai headquarters and a Jiaxing operation; the footer locates the company in Yuanhua Town, Haining. [1] That corporate relationship is not independently authenticated here.
- Workshop presentation
- The gallery displays eight entries using the same image URL. They do not establish eight production lines or a measured process inventory.
- Quality-system wording
- The introduction says production is managed according to ISO9001. This is not an authenticated current certificate.
- Credentials page
- The repeated image is an award plaque, not an ISO certificate carrying current holder/site/scope/validity information.
These observations come from the actual company galleries. [4] [5] Obtain the contracting entity, process/site details and original qualification documents when required. No visit, machine inventory, certificate badge or verified company-age claim is assigned.
Give a reason for changing the bearing
| Buyer’s reason | Installation evidence to send | Response to obtain |
|---|---|---|
| Temperature or chemical exposure | Actual temperatures, fluid/chemical identities, contact and duty. | Selected materials, cage/seal/lubrication compatibility and documented limits. |
| Electrical or magnetic requirement | Required assembled-bearing behaviour and how it will be evaluated. | Complete construction and test basis, not only a ring-material label. |
| Replacement in a rotating mechanism | Original designation, shaft/housing fit, loads, speed, shocks and alignment. | Exact drawing, clearances, allowed duty and application-specific rating basis. |
Junwang’s company-wide application list includes specialist fields. [1] It does not prove excavator or crane OEM suitability. For construction-machinery auxiliaries, explain the real shock, dust, sealing and mounting conditions rather than assuming directory inclusion is installation approval.
ISO 281’s publisher abstract describes conventional hardened-steel bearing load/life calculations. [6] It does not establish this ceramic product’s numbers. Require a justified ceramic construction/rating basis instead of borrowing a steel catalogue’s values.
Link the trial to one controlled construction
- 1
Define the supplied bearing
Align reference/drawing revision, component materials, tolerances/clearance and cage/seals with the intended installation.
- 2
Agree sample evidence
Request material and dimensional records and any actual required performance tests with conditions/acceptance. Define an installation trial relevant to the buyer’s reason for substitution.
- 3
Preserve the approved construction
Record changes requiring reapproval, lot identity, packaging and handling instructions. A broad “stock available” statement does not fix a material variant’s quantity or delivery date.
