I. Anohyeto titiriw a ɛwɔ thrust ball bearings mu wɔ nsu mu mmeae ahorow .
1. Nsɛm a ɛfa ho: .
Wɔde carbon steel (te sɛ GCR15) a ɛyɛ mmerɛw sɛ ɛbɛhyew wɔ nsu mu na ɛyɛ ball bearing a wɔde twetwe ade a ɛyɛ mpapahwekwa kɛse. Nhwehwɛmu nsɛm kyerɛ sɛ carbon steel bearing a wɔmmɔ ho ban no tumi rust kɔ 60% wɔ wɔn ani akyi bere a wɔde wɔn ahyɛ nsu pa mu nnafua 30 akyi (hwɛ 2021 nhwehwɛmu wɔ mfiridwuma mu nneɛma ho). Sɛ ɛho hia sɛ wɔde nsu a wɔde siw nsu ano di dwuma a, ɛsɛ sɛ wɔde dade a ɛnyɛ den (te sɛ 440C) anaa dɔte di dwuma mmom.
2. Srade a ɛyɛ huammɔdi:
Wɔbɛhohoro srade a wɔde srade gu mu a wɔde di dwuma wɔ amanne kwan so no anaasɛ wɔbɛma ayɛ emulsified bere a wɔde ahyɛ nsu mu no. Sɛ nhwɛso no, friction coefficient a ɛwɔ bearing a wɔde lithium-gyina srade so no kɔ soro 300% wɔ nnɔnhwerew 24 mu bere a wɔde ahyɛ nsu mu akyi (data fibea: SKF Technical Manual). Sɛnea ɛbɛyɛ na wɔde adi dwuma wɔ nsu ase no, ɛsɛ sɛ wɔpaw srade a nsu ntumi nkɔ mu (te sɛ polyurea-based grease) anaasɛ ɛsɛ sɛ wɔsesa srade a ɛyɛ den.
3. Nsɔano sintɔ ahorow:
Standard thrust bearings no nni seals, na ɛma nsu tumi kɔ raceways no mu tẽẽ. Sɔhwɛ ahorow kyerɛ sɛ bere a wɔayɛ adwuma wɔ nsu mu wɔ nsu a ɛsen 1 m/s mu nnɔnhwerew 10 akyi no, nsu a ɛkɔ mu no mu nsu a ɛbue no boro 90%.

ii. Ano aduru a ebetumi aba a wɔde bedi dwuma wɔ nsu ase .
1. bearing ahorow a nsu ntumi nkɔ mu titiriw:
- Material Upgrade: Sɛ nhwɛso no, Japan NSK "Aqua Series" de SUS304 dade a ɛnyɛ den na edi dwuma na ɛnkyerɛ sɛ nkannare biara nni hɔ wɔ nnɔnhwerew 500 nkyene a wɔde petepete sɔhwɛ akyi.
- Nsɔano Nkɔsoɔ: Mmienu-Hyɛn rɔba nsɔano (a wɔde NBR ayɛ) tumi siw nsuo 99% (a wɔagye atom sɛdeɛ ISO 281 kyerɛ no).
2. Nneɛma a wɔde bɔ wɔn ho ban foforo:
- Abɔnten so nsɔano katasoɔ: dan a wɔde IP68 ahyɛ mu ma a wɔde ka ho no ma ɛka kɔ soro bɛyɛ 20%, nanso ɛma nkwa nna kɔ soro mprɛnsa.
- Nsiesiei a wɔyɛ no daa: Ɛsɛ sɛ wɔsesa srade wɔ nnɔnhwerew 500 biara a wɔde yɛ adwuma no mu (wɔkamfo Klüber Aquatro 2 series kyerɛ).
iii. Nneɛma a wɔde di dwuma ho nyansahyɛ ahorow a mfaso wɔ so .
- Sɛ ɛyɛ tiawa-bere a ɛwɔ nsu ase dwumadi ahorow mu a: bearing a ɛyɛ mmerɛw a ɛwɔ bere tiaa mu nsu a ɛmma nsu ntumi nkɔ mu (te sɛ WD-40 a wɔde petepete so) betumi agyina nea ennu nnɔnhwerew 48 ano.
Wɔ bere tenten-bere a wɔde di dwuma wɔ nsu ase no ho: bearing ahorow a wɔayɛ ama nsu a ɛwɔ nsu ase (te sɛ THK DSA series) titiriw no ho hia. Eyinom bo bɛyɛ $80-$150 biara nanso ɛma wonya nnɔnhwerew 50,000 a wɔayɛ no sɛnea ɛsɛ.
Awiei: Sɛ́ ebia wobetumi de ball bearings a wɔde hyɛ mu adi dwuma wɔ nsu ase no gyina sɛnea wɔbɔ wɔn ho ban ne sɛnea wɔyɛ adwuma no so. Ɛsɛ sɛ wɔn a wɔde di dwuma no kari pɛ wɔ ɛka ne adwumayɛ mu, na wɔde pre-asɔ, nsu a ɛmma nsu ntumi nkɔ mu ho nhwɛso ahorow adi kan.
